Question

your aunt is building a garden in her backyard.she has 90ft of fencing to surroud it.if she wants the lenght to be 15 ft onger than the width , what should the dimensions of her garden be

Answer 1

Let w represent the width.

2w * 2(w+15) = 90
4w + 30 = 90
4w = 60
w = 15

Does that work?
15 + 15 + 30 + 30 = 90

Yep!
