Answer:
The perimeter 9+9+15+4+3+4pi=52.56 units.
The area is 25.12+135 which is 160.12 unit squared.
Step-by-step explanation:
Perimeter of this shape = perimeter of half circle + perimeter of the rectangle
Diameter of circle = 15-4-3 = 8
Radius of circle = 8/2 = 4
Perimeter of the shape = (2 x pi x 4)/2 + 15 + 9 + 9 + 4 + 3
= 4pi + 40 = 52.56 units (substitute pi = 3.14)
Area of shape = area of half circle + area of rectangle
= (pi x 4 x 4)/2 + (9 x 15)
= 25.12 + 135 = 160.12 unit squared
