Question

A rectangular pool is 21 meters wide and 28 meters long. If you swim diagonally across the pool, how many meters would you be swimming?

Answer 1

To figure this out, you must use the Pythagorean theorem.
That is were you take the width of the opject, and square it (21 squared). and take the length of the object and square it (28 squared),
 then add those together. (21 squared + 28 squared) = NUMBER
then take that number that you got, and find the square root of it. (√NUMBER)
and that's your answer.

So it would be: 35 meters
