The sides of a triangle are in the ratio of 2:3:4. If the measure of the shortest side of the triangle is 12 centimeters, what is the length of the longest side?

16 cm

18 cm

24 cm

36 cm

To answer this, we let x some factor that would agree or make the ratio given true. We calculate as follows:

2:3:4

2x:3x:4x

2x = 12

x = 6

Therefore, the length of the longest side would be 4x = 4 (6) = 24 cm, third option.
