Perimeter of the shape = 27.15 units.
Area = 32.3 units²
<h3>How to Find the Perimeter and Area of a Composite Shape?</h3>
The Perimeter of the shape = 1/2(perimeter of circle) + hypotenuse and height of the triangle
Perimeter = = 1/2(2π(5/2)) + [√(9² + 5²)] + 9 = 7.85 + 10.3 + 9 = 27.15 units.
Area = 1/2(area of circle) + area of triangle = 1/2(πr²) + 1/2(bh)
Area = 1/2(π2.5²) + 1/2(5)(9)
Area = 9.8 + 22.5
Area = 32.3 units²

6 more than means add 6. The product of 2 and N means multiply the two together.
C) 2N + 6 is the answer.
Hope this helps! :)
Answer:
x=40
Step-by-step explanation:
Area of a triangle = B*H/2
First, you have to find the relationship between the large triangle and the smaller triangle. 72 is three times as much as 24, so to find x, you would have to find the relationship between 120 and x. So, 120/3 = 40.
