The perimeter of a rectangular field is 220 yd. the length is 30 yd longer than the width. Find the dimensions

We are given the following equations:
  1. 220 = 2l + 2w
  2. l = w + 30
Plug (1) into (2)
2(w + 30) + 2w = 220
2w + 60 + 2w = 220

Combine like terms:
4w + 60 = 220

Plug 4w + 60 = 220 into the search engine, and we get w = 40.

Now plug w = 40 into equation (2)
l = 40 + 30
l = 70
