Answer:
≈ 189.3 cm²
Step-by-step explanation:
The shape is composed of a rectangle and a semicircle, then
area of rectangle = 15 × 10 = 150 cm²
The semicircle has a diameter of 10 cm , so radius = 10 ÷ 2 = 5 cm
area of semicircle = [tex]\frac{1}{2}[/tex] πr² = 0.5 × π × 5² = 12.5π cm²
area of shape = 150 + 12.5π ≈ 189.3 cm² ( to 1 dec. place )
