Question

Jacob was asked to build a fence around the glass area of his neighbors lawn. How many feet of fence does Jacob have to build?

Answer 1

For this, you can calculate the perimeter of the area painted with gray. The perimeter is the sum of all the sides of a geometric figure.

So, you have

$\begin{gathered} P=15ft+6ft+11ft+11ft+4ft+17ft \\ P=64ft \end{gathered}$

Because

$\begin{gathered} 17ft=11ft+6ft \\ \text{ and} \\ 4ft=15ft-11ft \end{gathered}$

Therefore, Jacob has to build 64 feet of fence.
