Question

What is the area of this composite shape?

Answer 1

Here,

In Right angle triangle,

base = 12 m

height = 8 m

Now,

◇ Area = 1/2*b*h

= 1/2*12*8

= 48 m^2

In semicircle,

radius = 4 m

Then,

◇Area" = 1/2*22/7*r^

= 1/2*22/7*4*4

= 25.14m^2

Again,

◆Total Area = Right triangle + semicircle

= (48+25.14) m^2

= 73.14 m^2

This is right answer...
