The areas of two similar triangles APQR and AXYZ are 12.96 cm² and 635.04 cm², respectively. If QR = 2.9 cm, then the length (in cm) of YZ equals:
Answer
The correct answer is C: 20.3. For similar triangles, ratio of areas = square of ratio of corresponding sides. √(635.04/12.96) = √49 = 7.
- A.30.4
- B.25.2
- C.20.3✓ Correct
- D.23.2
For similar triangles, ratio of areas = square of ratio of corresponding sides. √(635.04/12.96) = √49 = 7. So YZ = QR × 7 = 2.9 × 7 = 20.3 cm.
