Question

The side of a triangle are in the ratio 2:3:4.If the shortest side measure 6cm,what is the perimeter of the triangle?

Answer 1

6 + 9 + 12 = 27 cm

Answer 2

What you want to do is cross multiply

since 2/3 = 6/x, when you cross multiply, you get 2x=18 x=9

2:4 = 1:2 so you can just double 6
or
2/4 = 6/x 2x=24 x=12

Therefore the perimeter of the triangle is 6+9+12

Answer: 27

Answer 3

let the sides be 2x, 3x, and 4x
perimeter = 9x

given: 2x = 6
so, x = 3

perimeter = 9x = 9(3) = 27
