Question

a rectangular garden is 90 m long and 75 m broad.a path 5 m wide is to be built around it.find the area of the path and the cost of gravelling it at a rate of Rs 17 per m2

Answer 1

Area of original garden = 90 * 75 = 6750 m2m2

After path is added around rectangle, new length = 90 + 2*5 = 100 m

new breadth = 75 * 2*5 = 85 m

Area of rectangle with path = 100 * 85 = 8500 m2m2

So area of path = Area of rectangle with path - Area of rectangle without path

Area of path = 8500 - 6750 = 1750 m2
