The circular rug is placed on a square floor. The rug touches all four walls. How much of the floor space is not covered by the rug? The square floor is 14 feet for length and width.

The area of the floor = 14 * 14

The diameter of the rug is 14 feet.

The area of the rug is

A = pi * r^2

A = 3.14 * 7 * 7
A = 153.86

Subtract the area of the rug from the area of the floor.
