A rectangle is cut in half to create two squares that each has an area of 25. What is the perimeter of the original rectangle?

A. 20

B. 25

C. 30

D. 50

Area of a square:

A = s^2

We're given A = 25:

s^2= 25

s = 5

This means the rectangle width is 5.

The rectangle length is 2(5) = 10.

Perimeter of a rectangle:

P = 2l + 2w

P = 2(10) + 2(5)

P = 20 + 10

P =
