Question

The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of
first triangle is 9 cm, what is the corresponding side of the other triangle?
​

Answer 1

Answer:

answer is 5.4 cm

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 perimeters is

perimeter of Δ1 and Δ2

So,the side of triangle 2 is will be

$\frac{9}{side \: of \: Δ2 } = \frac{25}{15}$

=> side of Δ2 =

$\frac{9 \times 15}{25} = 5.4$

=5.4.
