The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm?

(1 point)

The total ratio of the sides is 3 + 4 + 5 = 12.

If the perimeter of the triangle is 90 cm, then the length of each side will be:
3/12 * 90 = 22.5 cm
4/12 * 90 = 30 cm
5/12 * 90 = 37.5 cm

Therefore, the length of each side is 22.5 cm, 30 cm, and 37.5 cm.
