Answer:
370.2
Step-by-step explanation:
We need to find the area of the square, and the area of the 4 semi circles and add them up.
The area of a square is given by the formula A = S², where the sides are 12. therefore:
12² = 144
4 semi circles are equivalent to 2 full circles. In order to find the area of the two circles, you can use the formula:
A = πr² ⇒ where r is 1/2 the diameter
A = π(6)² ⇒36π *2(because its two circles)
Area of the 2 full circles it 72π ≅ 226.19
Then the area of the figure: 144+226.19
370.19 ≅ 370.2
