Because we're treating the swimming pool as a standard rectangle, rather than a three dimensional shape, we can use the formula L * W = A to calculate the length of the pool.

Length * Width = Area

We've established two key bits of information, and with them we can solve for the final piece.

Length * 4 = 16

4l = 16

Divide both sides by 4.

l = 4

<h3>The length of the pool is 4 meters.</h3>

You can have a calculator add these numbers for you. Most will report the result as a decimal. There are fraction calculators on-line, if your graphing calculator does not have a fraction display mode.

If you want minutes, multiply the fraction (or decimal) by 60 minutes.
