Question

the rectangular Park 500 m long and 300 M wide has two Cross Roads intersecting and triangle inside of it passing through the middle of it with each Road parallel to its side calculate the area of the remaining park in ha if each road is 50m wide​

Answer 1

hope it will help

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
