Question

the perimeters of two similar triangles are 25cm and 15cm. if one side of the first triangle is 9cm, find the corresponding side of the second triangle

explain step by step I will mark them as brain list answer​

Answer 1

Answer:

similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.

The ratio of their perimeter is

perimeterofΔ2

perimeterofΔ1

=

15

25

So, the side of triangle2 will be

sideofΔ2

9

=

15

25

⟹sideofΔ2=

25

9∗15

=5.4.

Answer 2

Answer:

5.4 cm

Step-by-step explanation:

Let required side be x cm.

Since, both the triangles are similar,

So,

9/25=x/15

=>x=(9X15)/25

=>x=5.4 cm
