1.	two cross roads , each of width 5m , run at right angles through the centre of a rectangular Park of length 70 metre and breadth 45 and parallel to. it's sides. find the area of the roads. also find the cost of constructing the roads at the rate of rupees 105 per metre square
Answer» Answer: Rs 57750 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

Answer»

Answer:

Rs 57750

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
