2. The area of the semicircle = 64.3 m²

What is the Area of a Triangle?

Area = 1/2(base × height)

What is the Area of a Semicircle?

Area = 1/2(πr²)

1. Area of the Triangle = 1/2(base × height) = 1/2(10 × 8)

Area of the triangle = 40 m².

2. Use Pythagorean Theorem to find the hypotenuse of the triangle which is the diameter of the semicircle.

Hypotenuse = √(10² + 8²) = 12.8 m

Radius of the semicircle = 12.8/2 = 6.4 m

Area of the semicircle = 1/2(3.14 × 6.4²) = 64.3 m²
