The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first triangle is 9 cm, find the corresponding side of the second triangle.
plz guys hrlp me if you solve i will make brainliest

5.4cm

Step-by-step explanation:

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

The ratio of their perimeter is  

perimeterofΔ2          15

  =

perimeterofΔ1           25  

So, the side of triangle 2 will be  

  9  *  15                  15

 =  

 sideofΔ2                25

=  

⟹side of Δ2=           25  / 9∗15         =5.4.
