The perimeters of two similar triangles are 24 cm and 16 cm respectively. If one side of the first triangle is 9 cm long, then what is the length of its corresponding side of the other triangle?
Answer & explanation
Correct answer: option 1
Concept used :-
Ratio of perimeter of triangle = Ratio of Side of triangle
Triangle 1 : Triangle 2
Perimeter 24 : 16
3 : 2
So, Side 3 : 2
According to question,
3R = 9
1R = 3
Now, 2R = 2 × 3 = 6
The correct answer is Option (1) → 6 cm
