Question

two Cross Roads each 2 metre wide run at right angles through the centre of a rectangular field 90 m by 70 m such that each is parallel to one of sides of the rectangle find the total cost of covering the crossroads with red graven at rupees 60 per square metre and putting grass at the remaining portion of the field at rupees 50 Per square metre​

Answer 1

Step-by-step explanation:

Area of a rectangular park =l×b=64×38=2432m^2

Area of a horizontal road =l×b=64×2=128m^2

Area of a vertical road =l×b=38×2=76m^2

Common area =2×2=4m^2

Area of the roads =204−4=200m^2

Area of the remaining part of the park =2432−200=2232m^2
