Semi circle Area = 1/2 x 3.14 x 10x10 = 157
Quadrants Area = 1/4 x 3.14 x 20 x 20 = 314
How to find the different?

let shape ABF = area H
area of square = 20x20 = 400 cm²
area of quadrant = ¼x3.14x20x20
= 314 cm²
area H + area F
= area of square - area of quadrant
= 400 - 314
= 86 cm²
area of semi circle = ½x3.14x10x10
= 157 cm²
area H + area E
= area of quadrant - area of semi circle
= 314 - 157
= 157 cm²
area H + area F = 86
area H + area E = 157
area E - area F = 157 - 86 = 71 cm²
area of square = 20x20 = 400 cm²
area of quadrant = ¼x3.14x20x20
= 314 cm²
area H + area F
= area of square - area of quadrant
= 400 - 314
= 86 cm²
area of semi circle = ½x3.14x10x10
= 157 cm²
area H + area E
= area of quadrant - area of semi circle
= 314 - 157
= 157 cm²
area H + area F = 86
area H + area E = 157
area E - area F = 157 - 86 = 71 cm²
Thank you.
