Question

The length of sides of a triangle are in ratio 1/2 : 1/3 : 1/4

Answer 1

Step-by-step explanation:

We know that,

sum of all three sides of a triangle = 180

ATQ,

1/2x + 1/3x + 1/4x = 180

6x + 4x + 3x / 12 = 180

30x = 180×12

30x = 2160

x = 2160/30

x = 72

First side = 1/2 x = 1/2× 72 = 36

Second side = 1/3x = 1/3× 72 = 24

Third side = 1/4 x = 1/4× 72 = 18

So the sides are 36cm , 24 cm and 18 cm
