SOLUTION:

Step 1:

In this question, we are given the following:

Your geometry class goes on a field trip to the zoo.

If an 18-foot tall tree casts a 9 -foot long-shadow.

How tall is an adult giraffe that casts a 7 -foot shadow?

Step 2:

The details of the solution are as follows:


\begin{gathered} If\text{ 18 foot tall tree = 9-foot long shadow} \\ \text{ ? = 7 -foot long shadow} \end{gathered}
\begin{gathered} cross\text{ - multiply , we have that:} \\ 9\text{ x ? = 18 x 7} \\ Divide\text{ both sides by 9 , we have that:} \\ ?=\frac{18\text{ x 7}}{9} \\ ?\text{ = 2 x 7} \\ ?\text{ = 14 - feet tall tree} \\ \end{gathered}

CONCLUSION:

The adult giraffe is 14 - feet tall
