Answer 2

Answer:-

₹918

Step-by-step explanation:-

Area of the triangular field using heron's formula,

semi perimeter(s) = 51+37+20/2 = 54m

So, area = √s(s-a) (s-b) (s-c)

= √54(54-51)(54-37)(54-20)

= √54*3*17*34

= √93636

= 306m²

So, now, cost of leveling = area × rate

= ₹ 306 × 3

= ₹ 918
