The perimeter of a triangle is 48 inches and the sides are i the ratio of 3:4:5. Find the length of the longest side

1 answer:

4 0

First you do 3 + 4 + 5 = 12, so there are 12 parts to this ratio.

48 / 12 = 4, this means that each part of the ratio is worth 4 inches.

The longest side is worth 5 parts of the ratio.

4 * 5 = 20 inches
