To find the length of the longest diagonal of a parallelogram with sides 15 and 12 and an area of 54, you can use the formula for the area of a parallelogram: area = base × height. Rearrange this formula to solve for the height: height = area / base. Substitute the given values into the formula to find the height. Once you have the height, you can use the Pythagorean theorem to find the length of the longest diagonal. The diagonal's length is the square root of the sum of the squares of the two side lengths and twice the square of the height. Calculate the length of the longest diagonal using these steps.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
