Question

if ratio of corresponding sides of two similar triangles is 2:3 then find the ratio of their perimeter​

Answer 1

2:3 as the triangle is similar therefore the addition of sides will also be in the ratio of 2:3

Answer 2

Answer:

The ratio of their perimeter​ is 2:3

Step-by-step explanation:

1st Δ

let,

1st side =2a

2nd side=2b

3rd side=2c

∴perimeter=2(a+b+c)

2nd Δ

1st side =3a

2nd side=3b

3rd side=3c

∴perimeter=3(a+b+c)

so.

required ratio is =2(a+b+c)/3(a+b+c)

                            =2:3
