So you can you the Pythagorean theorem to solve this problem.

if each side of the square is a certain length x, then the square is made up of two right triangles.

the sides adjacent to the right angle are length x while the hypoteneus is the diagonal whcih measures 36 feet.

a^2 + b^2 = c^2

x^2 + x^2 = 36^2

2x^2 = 1296

x^2 = 648

x = 25.456

area of a square = x^2 = 648 ft^2

The area of a circle is pi * r^2

circumference is 2 * pi * r

so we have to make the other side look like what area equals:

c = 2pr

divide both sides by 2

c/2 = p* r

square both sides and get

(c^2)/4 = p^2 * r^2

now divide both sides by pi and get

(c^2)/(4*pi) = pi * r^2

compare to area equation

pi * r^2 = a

pi * r^2 = (c^2)/(4*pi)

So

a = (c^2)/(4*pi)

So

a = (37.68^2)/(4 * 3.14)

a = 113.04

circumference is 2 * pi * r

so we have to make the other side look like what area equals:

c = 2pr

divide both sides by 2

c/2 = p* r

square both sides and get

(c^2)/4 = p^2 * r^2

now divide both sides by pi and get

(c^2)/(4*pi) = pi * r^2

compare to area equation

pi * r^2 = a

pi * r^2 = (c^2)/(4*pi)

So

a = (c^2)/(4*pi)

So

a = (37.68^2)/(4 * 3.14)

a = 113.04

Get the area of the circle. Use this formula:

Area = * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2

Area = 3.14 * 16

Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is

Area = side^2

Area = 8^2

Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, D) 13.76 square yards is the answer to this question.

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :
