Question

A rectangular garden of size 220m * 160m having two cross roads , each 6m wide is running through its middle , one is parallel to length and the other is parallel to its breadth . Find the total cost of paving the road at the rate of ₹ 60 per square metre

Answer 1

Total Area=220×160
=35,200
Area of Paths=
220×6+160×6=
2280
Area of center=S×S
=6×6
=36
=2280-36=2244
Cost of painting road =
2244×60=
134640 rupees

Answer 2

area of rect 220×160=35200
area of road 220×6=1320+160×6=960
-6×6=36
total area of road 2244
cost of paving 60×2244=134640
