A rectangular grassy plot 110 m. by 65 m has a gravel path 2.5 m wide
all round it on the inside. Find the cost of gravelling the path at 80
paise per sq. metre.
Area of the plot = (110 x 65) m2 = 7150 m2
Area of the plot excluding the path = [(110 - 5) * (65 - 5)] m2 = 6300 m2.
Area of the path = (7150 - 6300) m2 = 850 m2
Cost of gravelling the path = Rs.850 * (80/100)= Rs. 680
