Answer:
Explanation:
so imagine each of the 4 white spaces are like 1/4 of a circle. In this case 3.5 cm would be the radius(r) of the circle, agree?
the area of a circle is pi * r²
pi =~3.14
circle area = 3.14 * (3.5 * 3.5)
circle area = 3.14 * 12.25
circle area = 38.465 cm²
Ok, now that we have the white area, the green area is basically the full area of the square minus the white area, agree?
the side of the square is 3.5 + 3.5, which is 7 cm
square area = 7 * 7
square area = 49 cm²
green area = 49 - 38.465
green area = 10.535 cm²
