We are given a rectangular rug with a uniform border. Let’s begin by sketching and labeling the dimensions of the rug and the rug’s border below.
We must determine the area of the rug that excludes the border. Thus, according to our diagram above, we must determine the product of W and L.
Note that the entire length of the rug is (L + 2x) and the entire width of the rug is (W + 2x).
Statement One Alone:
The perimeter of the rug is 44 feet.
We will use the formula for the perimeter of a rectangle, which is P = 2W + 2L. Using the information in statement one, we can now create the following equation for the perimeter of the rug:
2(W + 2x) + 2(L + 2x) = 44
2W + 4x + 2L + 4x = 44
2W + 2L + 8x = 44
We see that we do not have enough information to determine the value of WL. Statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.
Statement Two Alone:
The width of the border on all sides is 1 foot.
We know x = 1, but we still don’t know the value of either W or L. Thus, the information in statement two is not sufficient to answer the question. We can eliminate answer choice B.
Statements One and Two Together:
Using the information in statements one and two we know that 2W + 2L + 8x = 44 and that x = 1. So,
2W + 2L + 8(1) = 44
2W + 2L = 36
W + L = 18
Since there are many pairs of numbers that add up to 18, we can’t determine the exact values of W and L. Thus, we still do not have enough information to determine the value of WL.
Statement 1: does not provide the length or width individually. Length and width could be different. For example L = 22 and W = 2, or L = 11 and w = 4. So the area will vary. Not sufficient.
Statement 2: only the width of the border is given i.e 1 foot. Can not possible to calculate area. Not sufficient
Combine: Combining both will also not possible as its the same thing the area will be changing because we don't know specific value of length and width. Not sufficient. _________________

So from statement 1 we know perimeter = 44. Not sufficient to find area as we don't know individual sides. from statement 2 we know border is of 1ft. Not sufficient to find area as we don't know individual sides. Now combining both we know if the sides are x and y without the borders then 2{(x+2)+(y+2)} = 44 => x+y = 18. So x & y could be any possible combination that gives sum 18. So area will vary depending on the combination.

If we look at the original condition, we have to know the length and width of the rug. Also, we have to know width of the border. Hence, there are 3 variables in the original condition. In order to match the number of variables and the number of equations, we need to have 3 equations. The condition 1) and the condition 2) each has 1 equation. Hence, there is high chance E is the correct answer. In fact, we cannot know the width and the length of the rug even if we use the condition 1) and the condition 2). Hence the correct answer is E.
- For cases where we need 3 more equations, such as original conditions with “3 variables”, or “4 variables and 1 equation”, or “5 variables and 2 equations”, we have 1 equation each in both 1) and 2). Therefore, there is 80% chance that E is the answer (especially about 90% of 2 by 2 questions where there are more than 3 variables), while C has 15% chance. These two are the majority. In case of common mistake type 3,4, the answer may be from A, B or D but there is only 5% chance. Since E is most likely to be the answer using 1) and 2) separately according to DS definition (It saves us time). Obviously there may be cases where the answer is A, B, C or D.

1) It is given that the perimeter of the rug(Including the Border) is 44 feet. Which means 2l+2w=44 l+w=22, So we have multiple possibilities for l & w, hence INSUFFICIENT
2)Here we are only provided with the width of the border and no other information is provided, hence INSUFFICIENT
1+2 Combining both the answers we still do not have enough information of length and width to calculate the area of the portion of rug excluding the border.

Let us assume the length and width to be L and W respectively.
Statement 1: 2(L+W) = 44 L+W = 22 This statement does not provide information about individual length and width of rug. No information about border width. So, Insufficient. Statement 2: Border width is 1 foot. But, no information about length and width of rug. Clearly, Insufficient.
Combining both: Still we can't deduce unique values for L and W. Hence, Insufficient.

(1) The perimeter of the rug is 44 feet. (2) The width of the border on all sides is 1 foot.
statement 1: 2l+2w=44 so, l+w=22 insufficient..
statement 2: there is no info about length and width of rug. so, insufficient.
Combined (1)+(2) length of rug=l-(1+1)=l-2, width of rug=w-(1+1)=w-2 So, area of rug=(l-2)*(w-2) we can not find the are of rug for this unknown variable. So, insufficient... Is my explanation correct Bunuel? Thanks...

This question asks us to find the area of the white rectangle- as interpreted by the stimulus.
The rectangular rug shown in the figure above has an accent border. What is the area of the portion of the rug that excludes the border?
(1) The perimeter of the rug is 44 feet. (2) The width of the border on all sides is 1 foot.
Statement (1) tells us that the perimeter of the rug is 44 feet; though, we do know the ratio of the side lengths and therefore there are multiple possibilities for the width and length. For example, you could have a length of 12 and width of 10. I almost tried to be creative with this question and had this impulse to find some reason to apply the Pythagorean theorem; though, there is no need to because even if you did that you would not be able to calculate the length and width of the rectangle within the black rectangle. Insufficient.
Statement (2) tells us that the width of the border on all sides is 1 foot- however, we run into the same dilemma as statement one. Insufficient.
Hence, both statements taken together are insufficient.

it took me less than 5 secs to react to the right answer of this question. Of course, it is E, no information given to calculate the requirement of the question.

MathRevolution, Bunuel - This is OG question. Question statement says "The rectangular rug shown in the figure above has an accent border". In that case rug is a inside rectangular or outer one ? If it says rug has accent boarder then it should be inner rectangular and it has boarder. Please help to clarify.
