Question

The ratio of the side lengths of a triangle is 2:3:4. The shortest side is 15 inches. What is the perimeter? Explain. Pleas show your work. I will give brainiest to the best and first answer

Answer 1

Ratio of the sides of the triangles,

2 : 3 : 4

Let's consider each side to be

2x,3x and 4x

Therefore the perimeter of the triangle is,

2x + 3x + 4 x = 9x

The shortest side is 15 inches.

We know that the smallest value in the above ratio is 2

Therefore,

2x = 15 inches

x = 7.5 inches

☞Perimeter of the triangle

= 9x

= 9 * 7.5 inches

= 67.5 inches
