Answer:
E.200.5ft²
Step-by-step explanation:
To find the area of the composite figure we simply split it into two regular shapes, a half circle and a square, we then find the area of the two shapes individually and add them together.
Area of square = s² where s = side length
It appears the given side length is 12 so s = 12
Which means area = 12² = 144ft²
For semi circle
Area = 1/2(πr² ), where r is the radius
The side length of the square is shared with the diameter of the semi circle meaning that the diameter of the semi circle is 12
To convert to radius from diameter we simply divide by 2 so r = 12/2 = 6
We have area = 1/2(πr² ) and r = 6
So area = 1/2(π6²)
==> evaluate exponent
Area = 1/2(36π)
==> take one half of 36
Area = 18π
==> multiply 18 and π
Area = about 56.5
Finally we add the two areas together
Total area = 56.5 + 144 = 200.5ft²

Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
This means <u>"if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"</u>
<u />
let's cross multiply and solve for x:
<em>So width is 2/3 feet and length is 0.75 feet.</em>
<em>Converting back to inches (since we need the area in sq. inches):</em>
<em>2/3 feet = 2/3 * 12 = 8 inches, and</em>
<em>0.75 feet = 0.75 * 12 = 9 inches</em>
<em />
<em>Hence, area is 8 * 9 = 72 sq. inches.</em>
