Answer 2

length of the rectangular piece of land = 0.5km = 500m

breadth of the rectangular piece of land = 0.3 km = 300m

perimeter = 2(l+b) = 2(500+300) = 2(800) = 1600m

1 m of wire costs = Rs. 2

1600m of wire costs = 1600 × Rs. 2 = Rs. 3200

hence, for 1 row of wire it costs = Rs. 3200

for 4 rows of wire it will cost = Rs. 3200×4 =

Rs.12,800.
