What you're seeing here is a rectangle attached to a semi-circle.
To find the area of a rectangle, multiply the length times the width. (lw)
To find the area of a semi-circle, use this formula:

To find your answer, first get the two dimensions of the rectangle

and multiply.

Now look at the semi-circle. We can see that it has a diameter of 3. Since the radius is equal to half, 1/2 the diameter, our radius is then 1.5.

We can also calculate this manually:

Add the dimensions of both objects together now.

Your geometric figure has a total area of 24.5325 cm.
-3+5+6g=11-3g
6g+3g= 11+3-5
9g = 9
g=9/9=1
Answer:
The measure of each angle is 18°
Step-by-step explanation:
we know that
A <u><em>regular polygon</em></u> is a polygon whose all sides are equal and also all angles are equal.
so
In this problem

Solve for x



Substitute the value of x

therefore
The measure of each angle is 18°
