A tree is 11 feet tall and casts a shadow 8 feet tall. A building nearby casts a shadow that is 22 feet long. How tall is the building?

30.25 feet

Step-by-step explanation:

set up a proportion and cross-multiply:

let 'x' = height of building

11/x = 8/22

8x = 242

x = 242/8 = 30 1/4

You haven't listed the choices that go with the question, so
it's really tough to guide you toward the correct choice.

Sticking with whole numbers, here are all possible dimensions
of the rectangle:

Length  Width  Perimeter
     7            1           16
     6            2           16
     5            3           16
     4            4           16
