Answer 1

Answer:

width =6 m

length of first parallel road 100 m

area of first road 100×6=600sq.m

length of second road 80 m

area of second road =80×6=480 sq.m

area of the common part of cross road with 6 m width that lies at the

center of the park 6× 6= 36 sq.m

area of roads = area of first road +area of second cross road−common area

=(600+480)−36

=1080−25

=1055 sqm

cost of the construction per sq.m =Rs.95

total cost =1055×95=Rs 1,00,225
