Length of the rectangular plot = 400 m
width of the rectangular plot = 200 m
Area of the rectangular plot = 400 x 200 = 80,000 square metres
Cost of tiling = Rs 12/100 square metres
Total cost of tiling = 80000x12/100 = Rs 9600
l=400m
B=200m
Area=400×200m
Cost of tilling in 12 for 100m²
So the cost of tilling the plot is 80000×0.12=9600 costing
