Question

the length of a rectangular swimming pool is 50 yards and the width of the pool is 20 yards. what is the approximate length of the diagonal of this pool?

Answer 1

The length of a rectangular swimming pool = 50 yards

The width of a rectangular swimming pool = 20 yards

We can use the Pythagoras theorem to find the length of the diagonal.

`\begin{gathered} c^2=a^2+b^2 \\ c^2=50^2+20^2 \\ c^2=2500+400 \\ c^2=2900 \\ c=\sqrt[]{2900} \\ c=53.85\: \text{yards} \end{gathered}`

Therefore, the approximate length of the diagonal of this pool is 53.85 yards.

Option (A) is correct.
