Answer:
65.12 ft^2
Step-by-step explanation:
Patio's area = area of trapezoid + area of semicircle
Area of a trapezoid = 1/2 x (sum of the lengths of the parallel sides) x height
1/2 x ( 12 + 8) x 4 = 40 ft^2
Area of semicircle = (1/2)πr²
r = 8/2 = 4ft
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
(1/2) x 3.14 x 4^2 = 25.12 ft^2
Area of patio = 40 ft^2 + 25.12 ft^2 = 65.12 ft^2
t = 40
25.12
