Write and solve a proportion to find the height of the building. i need on finding the height with an understandable confused

Write and solve an equation of ratios:

9 ft          22 ft

=

h               99 ft

This is appropriate because h is greater than 9 ft.

cross-multiplying, we get 

9(99) ft^2 = 22*h*ft

Then h =40.5 ft (which is the height of the building)

Remark

Keep the objects on one side of the proportion and the shadows on the other side. The length of the shadows should be right across from the height of the of the object it represents.

Formula

Sub and Solve

Let the height of the building = x

x/99 = 9/22 Cross multiply.

22x = 9 * 99

22x = 891 Divide by 22

x = 891/22

x = 40.5

The height of the building is 40.5 feet <<<< Answer

i believe the answer is the polygon, heptagon.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
