To find the length of the longest side of the triangle, first, determine the scale factor by adding the parts of the ratio together (3 + 4 + 5 = 12). Then, divide the perimeter by the scale factor to find the length of one part. Finally, multiply the length of one part by the corresponding part in the ratio (5) to find the length of the longest side.

Longest side length = (Perimeter / Scale factor) * Ratio part = (48 / 12) * 5 = 4 * 5 = 20 inches

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.
