Two roads 3m wide have been constructed in the middle of a garden crossing each other at right angles, running parallel to the sides of the garden 35m long and 25 m wide. find the cost of the constructing the roads at the at the rate of 80 per m sq.
Step-by-step explanation:
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
