Question

The sides of a triangle are in the ratio 3:4:5. Describe the length of the longest side if the

perimeter is at least 60 inches.

Answer 1

Add the ratios: 3 + 4 + 5 = 12

Divide the perimeter by 12:

60/12 = 5

Multiply each ratio by 5:

3*5 = 15 inches

4*5 = 20 inches

5*5 = 25 inches

The length of the longest side is 25 inches.
