Question

Corresponding sides of two similar triangles are in the ratio of 2:3. If the area of the small triangle is 48 sq.cm, then the area of large triangle is:

• A. 72 cm²
• B. 108 cm²
• C. 32 cm²
• D. 162 cm²

Answer 1

Answer:

B. 108 cm²

Let A1 and A2 are areas of the small and large triangle. Then, A2/A1=(side of large triangle/side of small triangle) A2/48=(3/2)² A2=108 cm²
