A rectangle has two variables to consider, length and width. However, from the graph we can tell 2*Width = 1*Length. Thus the rectangle can be defined by one variable of width, and the length is two times width.

Statement 1:

We can count how many lengths and widths we need to add up but ultimately it will be some multiple of width = 36, thus we can solve for width and then the length. Sufficient.

Statement 2:

Same as above, sufficient.

Ans: D

Hey,
Can anyone explain in a simplified manner? I still don't understand how can we determine the width and length?

Thanks.

Bunuel,

How can we infer from the graph that 2*Width = 1*Length ? I considered length = x and width = y. So, the perimeter of the larger rectangle = 6(2x + y).

From (1), we get 3(x + 2y) = 36 and from (2), we get 2(2x + 5y) = 54 => we get values of x and y; thus, both statements together sufficient.

Pl. expln.

Look at the image. Notice that the length of 4 rectangles equals to the width of 8 rectangles. So, length = 2*width

length =x and width = y and if we carefully observe x =2y. so if we know x or y then sufficient to find perimeter of r large rectangle.

large rectangle perimeter = 12x +6y = 12x or 24y
1. length of darkened path on the right -3x+6y =>6x =>6x= 36 =>x=6=>12x =>72=> SUFFICIENT
2.length of darkened path on the left-4x+10y =9x= 54=> x=6=> 12x=>72= SUFFICIENT

from each statement you can get the wide of the tile, and from it the perimeter od the figure.
