Question

A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 1+1/3 larger, what is the percent increase in the area of the picture?

Answer 1

The percent increase in area of the picture is 40.33%

Step-by-step explanation:

Original area of the rectangular picture that measures 6 in by 9 in will be

Area= L*W

Area= 6*9= 54 in²

Increasing the dimensions by 1+ 1/3 larger will be

6+1+1/3 = 22/3

9+1+1/3=31/3

New area= 22/3 * 31/3 =682/9 = 75.78 in²

Increase in area = 75.78 - 54 = 21.78

Percent increase in area= percent increase/original area *100

Percent increase in area= 21.78/54 *100 = 40.33%
