Answer:

The corresponding sides of two similar triangles are 3 cm and 5 cm. if the perimeter of the smaller triangle is 18 cm, what is the perimeter of the other triangle?

30   →Ans.

Perimeter of the small triangle = 18

Perimeter of the bigger triangle = ?

Ratio of the sides = 3/5

Ratio of Perimeter = 18/x

Thus,

Ratio of the sides =Ratio of Perimeter

3/5 = 18/x

3x = 5(18)

3x=90

x=90/3

x=30
