Answer:
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
