Question

The sides of a triangle are in the ratio 1: 2:3. If the perimeter is 36 cm, find its sides..​

Answer 1

Ratio of sides of a triangle = 1:2:3

Let common ratio = x

Sides = x , 2x , 3x

Perimeter = Sum of all sides

Perimeter = x+2x+3x

36 cm = 6x

x = 36/6

x = 6 cm

Sides = x, 2x, 3x

= 6 cm, 12 cm, 18 cm
