Question

The length of a rectangle is 2 feet longer than the width. the perimeter is 28 feet. find the dimensions of the rectangle.

Answer 1

Perimeter=2l+2w

28=2l+2w
l=w+2

Substitute for l
28=2(w+2)+2w
28= 2w+4+2w
28=4w+4
24=4w
6=w

Plug the w value in
l=6+2
l=8

Final answer: Length=8 ft, Width=6 ft
