Question

The sides of a triangle are in the ratio 2 : 3 : 4 and its perimeter is 63 cm.
What are the lengths of its sides ?​

Answer 1

Step-by-step explanation:

Let the number be x

2x+3x+4x=54

9x=54

x=54/9=6

The sides of the triangle are

2x=2×6=12

3x=3×6=18

4x=4×6=24

Then,

We get the sides of the triangle are 12,18 and 24.

Answer 2

Step-by-step explanation:

Let the ratios be 2x,3x,4x

Perimeter = 63 cm

According to question -

2x+3x+4x=63

9x=63

x=63/9

x=7

1st side = 2×63=126

2nd side = 3×63=189

3rd side = 4×63=252
