The length of a rectangle is five times its width.
if the area of the rectangle is 405 in^2, find its perimeter.

The answer to your question is: Perimeter = 108 in

Step-by-step explanation:

Data

Length (l) = 5 width (w)

A = 405 in²

Perimeter = ?

Formula

Area = l x w

Perimeter = 2w + 2l

Process

                      405 = 5w x w

                       405 = 5w²

                     405/5 = w²

                       w = √81

                       w = 9 in

                       l = 5(9) = 45 in

Perimeter = 2(9) + 2(45)

                 = 18 + 90

                 = 108 in

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
