Answer:

Explanation:

The girl is 54 inches tall.

Her Shadow is 36 inches

The flagpole has a shadow of 90 in long

So set up a proportion

Whose Shadow Shadow Length Actual height

Girl 36 54

Flagpole 90 x

36/90 = 54 / x Cross Mulltiply

36x =90 * 54

36x = 4860 Divide by 36

x = 4860/36

x = 135 inches.

Comment

Do you need the height in feet?

That would be 135/12 = 11.25 feet or 11 feet 3 inches.
