What is the cost of laying artificial grass over 80m by 120m rectangular playing field if grass comes in 6m wide strips and cost £85 for 10m.

Answer 1

So 80 m by 120 m or 9600 m^2 have to be covered.
each 6 m by 10 m section or 60 m^2 costs £85
so we need 9600/60 or 160 of these sections.
at a total cost of £85(160) or £13600

Assuming the 6 m wide strips can be cut to any reasonable lengths
