To discourage weeds, the flower beds must be lined with landscape fabric over which mulch is placed to a depth of 5cm. Estimate the area and cost, if the landscape fabric is bought in rolls and costs 50 cent per meter squared, and the mulch, bought in bulk, costs $10 per meter cubed. There are 17 squares of flower beds and each square=1 meter.
Estimate the area and cost.?
Area = 17 meter square
volume =17*5/100 meter cube
cost(a) =17*5/100*10 $ [bulk item]
cost (b) =50*17 cents [ in rolls]
