Question

The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first triangle
9 cm, find the corresponding side of the second triangle.​

Answer 1

Answer:

5.4 cm

Step-by-step explanation:

In case of similar Δs,

⇒ [(Perimeter of 1st Δ)÷(Perimeter of 2nd Δ)] = [(Side of 1st Δ)÷(Side of 2nd Δ)]

i.e., The ratio of perimeter and side of both the Δs are equal.

∴ 25/15 = 9/x

∴ x = $\frac{9*15}{25}$

∴ x = 5.4 cm         ←ANSWER
