Question

The ratio of the sides of a triangle is 3:4:2.If the perimeter of the triangle is 72cm,find the lenghtin cm, of the sides of the triangle(picture is up on the question)

Answer 1

Let the constant stretch factor be x
then
3x + 4x + 2x = 72 Add the left side.
9x = 72 Divide by 9
x = 72/9
x = 8

Therefore the sides are
8*3 = 24
8*4 = 32
8*2 = 16
Total = 72 which checks.
