Answer 1

Answer:

57750

Explanation:

Answer

width =5 m

length of first parallel road 70 m

area of first road 70×5=350 sq.m

length of second road 45 m 

area of second road =45×5=225 sq.m

area 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.105

total cost =550×105=Rs 57750
