Question

Mr. Ron is preparing for his yoga class. He is placing rectangular mats on the floor of a rectangular room. The room is 32 feet long and 21 feet wide. Each mat is 6 feet long and 2 feet wide. He places 8 mats on the floor. The mats do not overlap. How much of the floor is left uncovered by the mats?

Answer 1

First, we find the area of the rectangular room.

Area of a rectangle is length x width

A = 32 x 21

A = 672

Second, we find the area of the mat

A = 6 x 2

A = 12

Since Mr. Ron put 8 mats, we multiply the area of the mat by 8.

A = 12 x 8

A = 96

Finally, subtract the area of the room by the area of the 8 mats.

672 - 96 = 576

576 feet of the floor is left uncovered by the mats
