The length of a rectangle is five times its width. If the area of the rectangle is 320m, find the perimeter

96 meters

Step-by-step explanation:

First set up

length*width=Area

(5w) * (w) = 320

5w^2=320

w^2=64

w=8

Now, find the perimeter.

Side1+Side2+Side3+Side4 = Perimeter

5w+w+5w+w = P

12w = P

Now Substitute your w (width)

12 (8) =

96 meters
