# The cost of farming a square land of Samar at the rate of Rs. 3.50 per sq. meter is Rs. 1,400. Let us calculate how much cost will be for fencing around its four sides with same height of Samar’s land at the rate of Rs. 8.50 per meter.

Answer :

1 m^{2} - - - Rs. 3.50

Area - - - - - Rs. 1400

So area = = 400m^{2}

Let the side of square land be L.

Since it is a square land, Area = L^{2}

Or L = = 20m

Perimeter of a square = 4L = 4 × 20 = 80m

1m - - - Rs. 8.5

80m - - - - - Rs. 80 × 8.5 = Rs. 680
