Anyone knows how to do this?

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

(60 + 30) * .25

90 * .25

90 + 22.5 = 112.50

112.50 is the maximum dollar amount Carmen can purchase.
