A rectangular gardien has a perimeter of 24 feet. The length is three less than twice the width. Find the length

So basically you have to find the width and the length that fits based on what they're giving you.

A basic perimeter equation= P=2L+2W

24=2W+2L

divide by 2 for each variable

so

12=2w+l

6=w+l

so, w+l could be 2+4, 3+3, or 1+5. now, if you input each of these into the equation

(2w)-3=l

so 2 could be 1,2,3,4, or 5.

2(1)-3=-1 so it can't be w=1 l=5

2(2)-3=1... it can't be w=2 l=4

2(3)-3=3 the length is 3

SO

you're answer for the length is 3

the answer to the expression is 83
