Answer:
71.76 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle with a missing half circle and a triangle.
area = area of rectangle + area of triangle - area of half circle
For the circle, radius = r = diameter/2 = 7 cm/2 = 3.5 cm.
area = LW + bh/2 - (pi)r^2/2
area = 10 cm * 7 cm + 7 cm * 6 cm/2 + (3.14)(3.5 cm)^2/2
area = 70 cm^2 + 21 cm^2 - 19.24 cm^2
area = 71.77 cm^2
Answer: 71.76 cm^2
