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 Sallly's garden?

Answer 1

2(4+3w)+w+w=72
8+6w+w+w=72
8+8w=72
-8 -8
8w=64
8w/8=64/8
w=8

BUT: You still need 1 more step to get your answer.

Plug your answer in:

4+3(8)=l
4+24=l
28=l

So the demensions of the garden are:

Width: 8 meters
Length: 28 meters
