A triangular piece of land has sides that are in the ratio of 3:5:7, with a total perimeter of 300 meters. What are the sides of this land?

  1. 60 m, 100 m, 140 m

  2. 70 m, 110 m, 120 m

  3. 50 m, 80 m, 120 m

  4. 65 m, 95 m, 140 m

Answer: A

Solution

Sum of ratio parts = 3 + 5 + 7 = 15. One part = 300/15 = 20 m. The sides are 3 × 20 = 60 m, 5 × 20 = 100 m and 7 × 20 = 140 m.
