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.
