Question

The length of Sally’s garden is 4 meters greater than 3 times the width. The perimeter of her garden is 72 meters. What are the dimensions of Sally’s garden

Answer 1

Width=8

Length=28

Explanation:

Width=x

Length=3x+4

perimeter is 2 lengths and 2 widths

2x + 2(3x+4)=72

2x+6x+8=72

8x=72-8

8x=64

x=8, so the width is 8

the length Is 3(8)+4 = 28
