Question

The length of a rectangle is two feet greater than twice its width. If the perimeter is 25 feet, find the width which of the following is correct 25=2L+2(2+2W)

Answer 1

w=7/2=3.5

Explanation:

width =w

length = l = 2w+2

25=2(l+w)= 2(2w+2+w) =2(3w+2)=6w+4

25=6w+4

6w=21

w= 21/6 = 7/2
