Answer:

Step-by-step 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.
