Since
/\ is an right angled isosceles triangle.
AB = BC = 7cm
<B = 90° •°• <C = <A = 45°
area of triangle = 1/2 × AB × BC
= 1/2 × 7 × 7 = 49/2 = 24.5cm²
For semicircle
r = d/2 = 7/2 = 3.5
area of semicircle = pi r² = 3.14 × (3.5)²
= 3.14 × 12.25 = 38.465cm²
Area of shaded region = 38.465 - 24.5 = 13.965cm²
