School name bal bhavna public school, laxmi Nagar​

Answer 1

Answer:

Equilateral triangle field with each side 84.5 m

=> Perimeter of equilateral triangle = 3 * side

=> = 3 * 84.5

=> = 253.5 m

Rectangular field with length 93.7 m & breadth 68.3 m

=> Perimeter of rectangle = 2*(l+b)

=> = 2*(93.7+68.3)

=> = 2*162

=> = 324 m

Since, 253.5m < 324m

Therefore, Shamu's agricultural field will need rope for fencing.
