Question

The perimeter of a rectangular window is 2626 feet. The width of the window is 33 feet more than the length. What are the dimensions of the​ window?

Answer 1

Alright, if the width is w and the length is l, 
l+33=w
2w+2l=2626.
Substituting w for l+33, we get 2(l+33)+2l=2626 and 2l+66+2l=2626 using the distributive property. Next, we get 4l+66=2626 and subtracting 66 from both sides, we get 4l=2560. Dividing by 4, we get 640=l and since w=33+l , w=673
