Area of the plot is 400 × 200 = 80000 m²

cost for tiling is 12 for 100 m²

⇒so for 1 m² the cost of tiling is rs 0.12

so the cost of tiling the plot is 80000 × 0.12 = Rs. 9600.

⇒so for 1 m² the cost of tiling is rs 0.12

so the cost of tiling the plot is 80000 × 0.12 = Rs. 9600.

Perimeter of rectangular plot = 2(400+200)

=1200

hence total cost is rs. 144
