Question

The lengths of the sides of a triangle are in the extended ratio 6:7:9, the perimeter of the triangle is 88 cm, what are the lengths of the sides?

Answer 1

let the side a=6x , b=7x and c=9x

p= 88

a+b+c = 88

6x+7x+9x = 88

22x = 88

x= 88\22

x= 4

now put these values in a, b and c

a= 24 , b=28 and c=36

Answer 2

Let the ratio be x.

6x,7x,9x

p=88

6x+7x+9x=88 cm

22x=88 cm

x=88/22

x=4 cm

6x=6×4=24 cm

7x=7×4=28 cm

9x=9×4=36cm

◆ The length of the sides of a triangle is 24,28,36.
