Answer:
189.3 square inches, 55.7 inches
Explanation:
Area = area of rectangle + area of semicircle
area of rectange = 10 * 15 = 150 square inches
radius of semicircle = 10/2 = 5
area of circle = (pi * 5^2)/2 = 12.5pi square inches
total area = 150 + 12.5pi = 189.3 square inches
total perimeter = perimeter of rectangle - left side + perimeter of semicircle
perimeter of rectangle = 10 + 15 + 15 = 40 inches
perimeter of semicircle = 10pi/2 = 5pi inches
total perimeter = 40 + 5pi = 55.7 inches
