To find the blue area: Blue= Area of the square - Area of the circle
Step 1: find area of the square
Area of a square= length × width
A= 12×12
A= 144 units²
Step 2: find Area of the circle
The diameter of the circle = 12 meters
Diameter= 2r
12m=2r
r=6meters
Area of a circle= πr²
A= πr²
A= π (6²)
A= 36π meters² ≈ 113.1 meters²
Final Step find the difference in Areas:
Blue= Area of the square(AS) - Area of the circle(AC)
AS= 144 m²
AC= 113.1m²
Blue= 144 m² - 113.1 m²= 30.90 meters² ≈ 31 meters²
Final Answer:
31 square meters
