alleryTwo triangles have areas in the ratio 49 : 64. The ratio of their corresponding sides is
A14 : 16
B8 : 7
C49 : 64
D7 : 8
Answer & Solution
Correct answer: D. 7 : 8
1. For similar triangles, ratio of areas equals square of ratio of corresponding sides.
2. Square root of 49/64 is 7/8.
3. Hence sides are in ratio 7 : 8.
