Question

The enrollment at an elementary school is going to increase from 700 students to 1330 students. A parents' group is planning to increase the rectangular 300 ft by 700 ft playground area to larger, similar rectangle area that is 600 ft by 1400 ft. What will be the difference between the smaller and larger playground areas?

Answer 1

300 x 700 = 210,000 square feet

600 x 1400 = 840,000 square feet

840,000 - 210,000 = 630,000 square feet difference
