Question

9. The perimeter of a triangle, the lengths of whose sides
are in the ratio 2: 3:4, is 99 cm. Find the length of
its three sides.

plz give me a step by step solution ​

Answer 1

Step-by-step explanation:

Ratio of three sides of triangle = 2:3:4

Let the three sides be 2x, 3x and 4x

Perimeter of triangle = 99cm

sum of 3 sides = 99cm

2x + 3x + 4x = 99cm

9x = 99cm

x = 99/9

11cm

Thus, the length of three sides are 2*11 = 22cm, 3*11 = 33cm & 4*11 = 44 cm
