Question

Tringle Ratio is 2 3 4 and perimeter is 90 then find sides

Answer 1

let the ratio of the triangle be =2x,3x,4x

its perimeter=90

now,

2x+3x+4x=90

9x=90

x=90/9

x=10
thus, the sides are2x=(2×10)=20
3x=(3×10)=30
4x=(4×10)=40

Answer 2

HEY

Sides are =2 :3 :4

Let it be = 2x:3x:4x

$2x + 3x + 4x = 90 \\ \\ 9x = 9 0 \\ \\ x = \frac{90}{9} \\ \\ x = 10 \\ \\ 2x = 2 \times 10 \\ = 20 \\ \\ 3x = 3 \times 10 \\ = 30 \\ \\ 4x = 4 \times 10 \\ = 40$

THEREFORE

Sides = 20, 30,40
