Answer 1

Attached is the complete question with the semi circular design.

Answer:

9.8 m²

Explanation:

From the image, we can see that;

Diameter = 5 m

That means radius; r = 5/2 = 2.5 m

Now, formula for area of semi circle is;

A = ½πr²

A = ½ × π × 2.5²

A = ½ × 22/7 × 6.25

A ≈ 9.8 m²

Area of semi circular lawn = 9.8 m²
