Question

the diagonal of a rectangular swimming pool measures 19 yd if the length of the pool is 15 yd which measurement is closest to the width of the pool?

Answer 1

11.67 yards

Step-by-step explanation:

From the above figure, we can use the Pythagorean theorem to find the width of the pool as shown below;

`\begin{gathered} 19^2=15^2+w^2 \\ 361=225+w^2 \\ 361-225=w^2 \\ 136=w^2 \\ \sqrt[]{136}=w \\ \therefore w=11.67\text{ yards} \end{gathered}`
