The left side is a half circle.
The area of a circle is PI x r^2

The diameter of the circle would be the height of the rectangle, given as 10 feet.
The radius is 1/2 the diameter, so 5 feet.

The area of half the circle is (3.14 x 5^2) / 2 = 39.25 square feet.

The area of the rectangle is 20 x 10 = 200 square feet.

Total area = 200 + 39.25 = 239.25 square feet.

Since ΔABC ~ ΔEDC, ∠B = ∠D.

Since both triangles appear to be similar, the corresponding angles are the same, and corresponding sides are the same or have the same ratio.

We can write an equation to resemble the problem:

8x + 16 = 120

Solve for x.

8x + 16 = 120

~Subtract 16 to both sides

8x + 16 - 16 = 120 - 16

~Simplify

8x = 104

~Divide 8 to both sides

8x/8 = 104/8

~Simplify

x = 13

Therefore, the answer is 13.

Best of Luck!
