Answer 1

The area of the figure is 297 square units

The figure shown is made up of a rectangle and a semicircle.

Area of the figure = Area of the rectangle + Area of the semicircle

Get the area of the semicircle:

$A=\frac{\pir^2}{2} \\A=\frac{3.14\times10^2}{2} \\A=3.14\times 50\\A_s=157 units^2$

Get the area of the rectangle:

$A_r = Length \times Width\\A_r=7\times 20\\A_r=140units^2$

Area of the figure = 157 + 140

Area of the figure = 297 square units

Hence the area of the figure is 297 square units.
