Let say Area of Square lawn = A m²
cost of grassing a square lawn of 1 m² = 1.35 Rs
cost of grassing a square lawn of A m² = 1.35A Rs
cost of grassing a square lawn of A m² = 72037. 35 Rs

Circumference = 4 * side = 4 * 231 = 924 m
Two times wire = 2 * 924 = 1848 m
cost of fencing it with wire two times at ₹2.85 per meter
