29Area of rectangle plus semicircle

A garden is a 10 m by 6 m rectangle with a semicircle on one of its 6 m sides. Find the total area of the garden. Give the answer to 1 decimal place.

The garden's total area is 74.1 m². The rectangle gives 10×6 = 60 m², and the semicircle on the 6 m side (radius 3) gives ½π(3)² ≈ 14.1 m²; adding them gives 60 + 14.1 = 74.1 m².
