Answer 1

Given:

Rectangle and semi-circle

To find:

Area of formulas for the composite figure

Solution:

The first shape is rectangle.

Rectangle have base and height.

Area of rectangle :

Area = base × height

$A=bh$

The second shape is semi-circle.

Area of the circle formula:

$A=\pi r^2$

Semi-circle is half of the circle.

Area of semi-circle formula:

$A=\frac{1}{2} \pi r^2$

The formulas needed to calculate the composite figure is $A = bh, \ A=\frac{1}{2} \pi r^2$.
