that both sides are 5 what is the length

Answer:
7 inches
Step-by-step explanation:
I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l
let P represent the perimeter of the window in inches
let w represent the width of the window in inches
let l represent the length of the widow in inches
(L is l whereas one is 1)
So we know w=5 and P=24
This lets us have the equation 24= 2 x 5 + 2l
24=10 + 2l
14=2l
7=l
