Question

The side of a triangle are in the ratio 2:3:4.if it perimeter is 54cm, find the length of the side of the triangle

Answer 1

the three sides of the triangle let be 2 x 3 x 4 x now perimeter of the triangle is equals to 54 that is equals to a + b + c =54

2x +3x+4x=54

9x=54

x=54/9

x=6

2x=2×6 =12

3x=3×6=18

4x=4×6=24

Answer 2

PERIMETER=54cm

Ratio = 2:3:4

Sum of ratio = 9

1st part(2)=2/9×54

=12 cm

2nd part(3)=3/9×54

=18cm

3rd part(4)=4/9×54

=24cm
