(E) 10/3 by 20/3


Given that P = 2l + 2w = 10, where l and w are the length and width in feet, respectively. Since, also given that l = 2w, then we have that 2l + l = 10 --> l = 10/3 --> w = l/2 = 10/6 = 5/3.

Answer: B.

(E) 10/3 by 20/3


L = 2W

Perimeter = 2(L+W) = 2(2W + W) = 6W = 10(given)
W = 10/6 = 5/3
L = 2W = 10/3

Answer will be B
Hope it helps!

(E) \frac{10}{3} by \frac{20}{3}

Relatively easy question, except for the confusing term - "twice as long as it is wide", which I happen to screw up over. Did someone happen to compile a list of these confusing statements in word problems? If so, please do share, it would be immensely helpful for me, and I am sure for other members as well.


Ya its quite easy....

twice as long as it is wide means : l=2w

Given p=10
2(l+w)=10
l+w=5
2w+w=5
w=5/3
and l = 10/3

If u feel difficult in understanding "twice as long as it is wide", since length should be always greater than width and here it is twice l=2w

(D) 3 by 6
(E) 10/3 by 20/3


my answer was B. Answer Key says E.



Width = x
Length= 2x
Perimeter = x+x+2x+2x = 6X
6x = 10
x= \frac{5}{3}

Therefore, dimensions are:
Width = \frac{5}{3}
Length = 2*\frac{5}{3} = \frac{10}{3}


B all the way

We can eliminate C,D,E as not giving 10 feeet as perimeter. In choice A, 3/2=1.5 and 7/2=3.5 so it is not double difference. The answer is B
