Question

Two cross roads each of width 5m, runs through the centre of a rectangular park of length 75 m and breadth 55m.
a)Find the area of the paths.
b)Find the area of the park excluding the roads.

Answer 1

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 centre 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
