Question

a rectangular plot of land measures 95 m by 72 M inside the plot, path of uniform width of 3.5 M is to be constructed all around the rest of the plot is to be laid with grass find the total expenses involved in constructing the path rupees 80 per m sq and laying the grass at rupees 40 per metre

Answer 1

Cost of laying the grass = area×cost
= 95×72×40
= 6840×40
= ₹273600
The length and breadth of the plot with path are length and breadth of the plot +(2×3.5)

Therefore,
Area of path = 102×79-95×72
= 8058-6840
= 1218 m square
Cost of constructing the path = 1218×80
= ₹97440
