Answer & Step-by-step explanation:
The covering for the window is also the area of the figure. First, find the area of the rectangle:
A=l×W
6×3=18
Now find the area of the semi circle:
A=πr²/2
Insert the values. The radius is half the diameter, which is 3, so:
3.14×1.5²/2
3.14×2.25/2
7.065/2
3.5325
Add to the area of the rectangle:
21.5325
The area of the window is about 21.5 units²
