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
