Question

a rectangular swimming pool is 15m wide and 39m long. Caculate the length of a diagonal

Answer 1

This is a Pythagorean Theorem question. The formula for this is a² + b² = c² where c represents the diagonal.

Since you're given the length and width, you can just plug them into the "a" and "b".

You should get 15² + 39² = c² or more simply = 225 + 1521 = c²

1746 = c². Square root to get the diagonal. Should be between 41 and 42 (I'll let you get the exact answer). Don't forget to include the unit of measure (meters!)

I hope this helps! Good luck!
