Answer» Answerwidth =5 mlength of first parallel road 70 marea of first road 70×5=350 sq.mlength of second road 45 m area of second road =45×5=225 sq.marea of the common PART of cross road with 5 m WIDTH that lies at the center of the park 5×5 = 225 sq.m area of roads = area of first road +area of second cross road−common area =(350+225)−25=575−25=550sqm cost of the construction per sq.m =Rs.105total cost =550×105=Rs 57750
