Question

Two cross roads each of width 5 M run at right angles through the centre of a rectangular Park of length 70 and breadth 45m parallel to its sides find the area of the roads also find the cost of constructing the road at the rate of ₹105 per metre square

Answer 1

area of roads= 5*45+5*70
                     = 225+350
                     = 575-25          (roads will intersect each other at a square of                           = 550m                                 side 5 hence 25 is subtracted)

cost=550*105
       = 57750 rs
