Question

the new artificial turf will cost $9.50 per square meter. if the field is 0.1020km by 0.0640km, how much will it cost the club to add the artifical turf to thier field

Answer 1

The dimensions of field are $0.1020 km\times 0.0640 km$. The area can be calculated as follows:

$A=l\times b=0.1020 km\times 0.0640 km=6.526\times 10^{-3}km^{2}$

Converting $km^{2}\rightarrow m^{2}$,

1 km =1000 m

Thus, $1km^{2}=10^{6}m^{2}$

or, $6.526\times 10^{-3}km^{2}=6.526\times 10^{3}m^{2}$

Since, cost of new artificial turf is $\ 9.50/m^{2}$, thus, cost for $6.526\times 10^{3}m^{2}$ will be:

$Cost= \ 9.50/m^{2}\times 6.528\times 10^{3}m^{2}=\ 62016$

Therefore, cost of artificial turf for field will be $\ 62016$.
