Answer:
56.5 meter square and rs2825
Step-by-step explanation:
curved surface area of cone
=πrl
22/7*2.8*2
=17.5
curved surface area of cylinder
2πrh
=2*22/7*2*2.1
=26.4
area of the base
=πr*r
22/7*2*2
=12.5
so,
total surface area of ⛺=17.6+26.4+12.5=56.5 square metres
per meter square cost=56.4*500=rupees,2825
