Perimeter of a vegetable garden

Question

The perimeter of a vegetable garden is 270 yards. The length of the garden is 15 yards more than twice the width. What are the dominions of the garden?

Answer 1

Assuming the garden is a rectangle in shape perimeter = 2(length + width )

 length = l = 15 + w ( w = width )

perimeter = 2( w + w + 15) = 270

2w+15 = 135

2w= 120

w=60in

l = 60+15 = 75in
