Answer:
60.56m2
Step-by-step explanation:
Since figure A is a semi circle and figure c as well
We can combine both make a circle
FigureA and C =2semicircle= circle
Area of a circle =πr^2
" " " =3.14*2^2
" " " =12.56m^2
Since the diameter is 4m
Therefore radius =2m
Figure B
A= bh
A= 12*4
A=48m^2
Composite figure
12.56+48=60.56m^2
The mistake was they neglected the fact that figure A and figure B are both semi circles.
