Answer 3

(Rectangle)
A=lw
A=(8cm)(5cm)
A= 40cm

(SemiCircle)
A = 12 π r 2

1
A = 2 π(4 cm)

A= 25.13

Add the areas of the simpler figures together to find the total area of the composite figure.
Area of rectangle + Area of semicircle

22 40cm +25.13cm

The area of the composite shape is around 65.13 cm
