Question

4. The length of a rectangle is 4 more than its width. The perimeter of the rectangle is 60cm.

Answer 1

Step-by-step explanation:

let width = w

if width = w, then length = w + 4

Therefore the perimeter is 2w + 2(w+4)

2w + 2(w+4) = 4w + 8

perimeter = 60cm

4w + 8 = 60

-8

4w       = 52

divide each side by 4

w = 13

length = w+4

therefore, length = 17
