A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2

7. Isosceles, Right
8. Isosceles, Obtuse
Isosceles means the triangle has two equal sides, we know the two sides are equal in both because of the marking line.
The first one is Right because one angle is 90 degress, the second one is Obtuse because one angle is greater then 90 degress.
Answer:
2 ( m + 2 m) = 36 is the required linear equation
Length of the rectangle is 12 ft and width = 6 ft
Step-by-step explanation:
Let the width of the rectangle = m ft.
So, the length of the rectangle = 2m ft.
Perimeter of rectangle = 36 ft
Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)
⇒2 ( m + 2m) = 36
or, 2 x 3m = 36
⇒ 6m = 36 , or m = 36/6
⇒ m =6 ft
So, the Width of the rectangle; = m = 6 ft
and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.
Simple area working out:
Area of a triangle: L x W
———
2
Area of a square: L x W
17 (L) x 17 (H) = 289cm^2
289
——- = 144.5cm^2

There are 4 triangles so:
144.5 x the amount of triangles (4) = 578
Add everything together:
578 + 289 = 867
Answer: 867
