Question

2. A tennis court is 78 feet long by 36 feet wide, If Sydney runs along the edge of the court twice, how for will she run

Answer 1

Lets draw a picture of our tennis court:

The Perimeter P of the tennis court is

$\begin{gathered} P=78+78+36+36 \\ P=228\text{ ft} \end{gathered}$

Since Sydney runs along the edge of the court twice, she runs 2xP, that is, 2x228 ft. So, Sidney runs 456 feet.
