Question

three sides of triangle are in the ratio of 2:3:4 given perimeter =13.5

Answer 1

let the angles be named as x
2x+3x+4x=13.5
9x=13.5
x=13.5/9
x=1.5


2x=2(1.5)
=3.0

3x=(1.5)
=4.5

4x=(1.5)
=6.0


here is your answer
if these types of questions come in your exam then you have to do like this

Answer 2

let one side = 2x

2nd side = 3x

3rd side = 4x

perimeter = sum of all sides = 13.5

according tot he sum,

2x+3x+4x = 13.5

9x = 13.5

x = 13.5 /9 

x = 1.5

one side = 2x = 2*1.5 = 3cm

2nd side = 3x = 3*1.5 = 4.5 cm

3rd side = 4x = 4*1.5 = 6cm
