A rectangle has a base of 3 inches and a height of 9 inches. If the dimensions are doubled, what will happen to the area of the rectangle?

A) It will be half of the original size.

B)It will be the same as the original size.

C) It will be four times the original size.

D)It will be one-fourth the original size.

Respuesta :

The answer is C -------------------
If the dimensions are doubled then the area will be four time the original size.

For example:

A of the original = 3*9 = 27
A of the doubled dimensions = (3*2)(9*2) = (6)(18) = 108

108/27 = 4

So the area of the double dimension rectangle is 4 times the original size.

Hope this helps :)
