The area of the figure can be determined by expression the figure as two shapes.
A semicircle and trapezium;
Area of shape = Area of semicircle + Area of trapezium
Now;
Area of semicircle =
Where r is the radius, which is = 2cm;
Area of semicircle = = 6.28cm²
Area of trapezium;
=
a and b are the base length = 6cm and 10cm
h is the height = 4cm
