Question

the sides of triangle are in the ratio 2:3:4 and its perimeter is 63 cm what are the length of its sides.

Answer 1

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

sum of sides = 2x + 3x + 4x = 9x

Given sum of sides is 63 cm

So 9x = 63

x = 63/9 = 7

2x = 2*7 = 14

3x = 3*7 = 21

4x = 4 * 7 = 28

So the sides of the triangle are 14cm, 21 cm and 28 cm

Answer 2

Hey friend!

The formula for the perimeter of triangle is
Side a + side b+side b+side c

Now let's find the sides
2:3:4=63
2:3:4=9 (2+3+4)

So,
63/9
= 7
Now multiply 7*(2:3:4)
= 14:21:28
So the length of sides r 14,21,24 cm
