Question

Help. The lenght of a rectangle is three times the width and its perimeter is 2 feet. Find the lengh of each side.

Answer 1

Explanation:

L=3W

P=2(L+W), given P=2 and L=3W we have

2(3W+W)=2

2(4W)=2

4W=1

W=1/4, since L=3W

L=3/4

So the side lengths are 1/4 ft by 3/4 ft

(or 3 in by 9 in)
