Question

A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture

Answer 1

27.7% larger

Explanation:

6 x 113% = 6.78

9 x 113% = 10.17

Old Area = 9 x 6 = 54 sq in

New Area = 6.78 x 10.17 = 68.95

(New - Old) ÷ Old = .277 = 27.7%
