Question: Two triangles are similar with a ratio of their corresponding sides as 3:5. If the area of the smaller triangle is 27 cm², what is the area of the larger triangle?
Options:
Correct Answer: 75 cm²
Solution:
Area ratio = (side ratio)² = (3/5)² = 9/25. Let area of larger triangle be A. 27/A = 9/25, A = 27 * (25/9) = 75 cm².
