The perimeters of two similar triangles are 36 cm and 24 cm, respectively. Find the ratio of their areas
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 9: 4.
Given that
The perimeters of two similar triangles are 36 cm and 24 cm
The ratio of their areas = The ratio of the square of perimeters of the corresponding triangles
Hence, the required ratio = (36/24)2 = (3/2)2 = 9/4
= 9 : 4
