a)2500 cm of plastic sheet
b)18 m, rs 270
c)rs 1750
Step-by-step explanation:
formula of area =l*b
a)the side =50 so, 50*50=2500cm
therefore, 2500 cm of plastic sheet is required
b) length =4.5m , breadth = 4m
4.5*4=18.0 area required is 18.0
18.0*150=2700
cost of carpeting=rs2700
c) l=3.5m b=2
3.5*2=7m
7*250=rs 1750
so the cost of tiling is rs 1750
