Can anyone help with this?

1.72

Step-by-step explanation:

if the Length is 4, the radius of the circle is 2, so the area is 4π. You have to divide by 2 because it is a semi-circle so it is 2π. Since the radius is 2, the width of the rectangle is also two. The area of the rectangle would be 8. 8 - 2π = 1.72

I hope this helps!

(Also if it is correct, can I have brainliest?)

Step-by-step explanation:

first find the area of the semi circle

1/2πr²

1/2π(2ft)²

1/2π4ft²

6.2831853071795864ft²

area of shaded portion

area of a rectangle=length x width

4ftx2ft(2is half the diameter)

8ft²

subtract are of semi circle from the area of the rectangle

8ft²-6.2831853071795864ft²

1.7168146928204135ft²

2,600 divided by 80 = 32.5
