Question

The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first

Answer 1

Answer:

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.
