Question

The perimeter of a rectangle is 68cm, The length is 4 cm more than its width. Find the dimensions of the rectangle.

Answer 1

let the width be w then the length is w + 4

so then using the perimeter information

68 = 2w + 2l

or

68 = 2w + 2(w + 4)

you now have an equation in 1 variable you can solve

68 = 2w + 2w + 8

or

68 = 4w + 8

so just solve for w

when you get the width, add 4 to it to find the length
