Answer:
The total surface area is 145.12 sq.m.
Step-by-step explanation:
We are supposed to find the surface area of given figure
Length of rectangular part = 15 m
Breadth of rectangular part = 8 m
Area of rectangular part =[tex]Length \times Breadth = 15 \times 8 = 120 sq.m.[/tex]
Diameter of semi circle = 8 m
Radius of semicircle = [tex]\frac{8}{2}=4 m[/tex]
Area of semicircle = [tex]\frac{\pi r^2 }{2}=\frac{3.14 \times 4^2}{2}=25.12 sq.m.[/tex]
Total surface area = 120+25.12=145.12 sq.m.
Hence The total surface area is 145.12 sq.m.
