Question

20. A field in the shape of an equilateral triangle with side 225 m is fenced with three rounds of rope. Another field, rectangular in shape, of length 200 m and breadth 125 m is fenced with two rounds of rope. Which field requires more rope and by how much?​

Answer 1

Answer: 725

Step-by-step explanation: perimeter of equilateral triangle = 3 x 225 = 675

Three rounds of rope = 675 x 3 = 2025

Perimeter of rectangular = 2(200+25) = 2 x 325 = 650

Two rounds of rope = 2 x 650 = 1300

So subtract 2025 - 1300 = 725
