Question

A rectangular garden has a perimeter of 172 feet. The length of the garden is 24 feet more than the width. What are the dimensions of the garden?

Answer 1

alright, first I think you would do 24+24 which is 48, then subtract that from 172, and you get 124, divide that by 2 and you should get your answer I thnk

Answer 2

let l = length and let w=width.

l=w+24 (saying that it order for width to be equal to length, you would add 24 more to the width. The width is shorter).

P=2(w+l)
172=2(w+l)
172=2(w+w+24)
172=2(2w+24)
86=(2w+24)
86=2w+24
62=2w
w=31

so, l=w+24 l=31+24=55

SO 55 and 31,

Checking....

2(55+31)=172
2(66)=172
172=172
