Question

The sides of a triangle are in the ratio $2:3:4$ the longest side is $20$ centimeter more than the shortest side. Calculate the length of all three sides.

Answer 1

Let length of 1 side=$2x$,

Let length of 2 side=$3x$,

Let length of 3 side=$4x$

According to question,

$4x-2x=20$

=> $2x=20$

=> $x=10$

So,

length of 1 side=$20$,

length of 2 side=$30$,

length of 3 side=$40$
