A Correct answer
Explanation

Area of circle = pi * r^2 = (22/7) * 7^2 = 154. Area of semicircle = 154 / 2 = 77 m^2.

AI explanation

Using the formula for the area of a semicircle, Area = (1/2) * * radius^2, we substitute the given radius. The calculation is (1/2) * (22/7) * 7^2, which simplifies to (1/2) * 22 * 7. This results in an area of 77 m^2.
