EXPLANATION:
-We must first know what data the exercise gives us.
-We must formulate the exercise based on the data we have, knowing that in the end the total value must be 120
-To find the width value we must work with an unknown or variable which in this case will be w.
-Since a rectangular court has two widths and two lengths, we propose the exercise as follows:
[tex]\begin{gathered} P=120\text{ L}=14\text{ feat }w=? \\ \text{widht}+widht+14+14=120 \\ 2w+28=120 \\ 2w=120-28 \\ 2w=92 \\ w=\frac{92}{2} \\ \textcolor{#FF7968}{w=46} \\ 46+46+14+14=120 \end{gathered}[/tex]
