Step-by-step explanation:

The formula for determining the area of a square is expressed as

Area = L²

Where

L represents length of each side of the square.

The side of the square is field us 12 meters long. Therefore

Area of the square field = 12² = 144ft²

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents radius if the circle.

π is a constant whose value is 3.14

Diameter of the circular area covered by the sprinkler is 12 meters.

Radius = 12/2 = 6 meters.

Area of the field covered by the sprinkler would be

Area = 3.14 * 6² = 113.04ft²

Therefore, the area of the field that is NOT reached by the sprinkler would be

144 - 113.04 = 30.96ft²
