Question

An artist wants to reduce the size of a drawing using a scale factor of 3:1 . The original drawing has an area of 720 square inches.

What is area of the new drawing?

Answer 1

The answer is 80

Explanation:

We know that we have to reduce...so the answer has to be smaller than 720!

Because it's 720 inches squared, we must square our scale factor of 1/3 which equates to 1/9.

1/9 * 720 = 80.
