Question

The sides of a triangle are in the ratio 7:5:3 and its permimeter is 30 cm. Find
the lengths of sides.​

Answer 1

Answer:

14 cm, 10 cm, 6 cm

Step-by-step explanation:

let the 3 sides of the triangle be 7x, 5x, 3x

perimeter=30 cm

7x + 5x +3x = 30

15x=30

so, x=2

7x=7 x 2= 14 cm

5x= 5 x 2= 10 cm

3x=3 x 2= 6 cm

Answer 2

Step-by-step explanation:

first side =7x

second side=5x

third side =3x

perimeter=a+b+c

30=7x+5x+3x

30=15x

x=30/15

x=2cm

so a=7(2)=14cm

. b=5(2)=10cm

. c=3(2)=6cm

hope this answer will help you!!
