For this problem we can start estimating the area for the 8 people
[tex]A=\text{ 6ft}\cdot6ft=36ft^2[/tex]And we also know that 8 people fit on this area
Then we can find the total area for the new structure (A1) but first we need to convert first 2yd to ft and 3 mi to ft, we know that:
1 yd= 3ft and 1 mi = 5280 ft.
[tex]\text{ 2yd}\cdot\frac{3ft}{1yd}=\text{ 6 ft, 3 mi }\cdot\frac{5280\text{ ft}}{1mi}=\text{ 15840 ft}[/tex][tex]A_{1\text{ }}=2\cdot6ft\cdot15480ft=190080ft^2\text{ }[/tex]And then we can use a proportional rule given by:
[tex]\frac{8\text{ people}}{36ft^2}=\text{ }\frac{x}{190080ft^2}[/tex]And solving for x we got:
[tex]x=190080ft^2\cdot\text{ }\frac{8\text{ people}}{36ft^2}=\text{ 42240 people}[/tex]And for this case the final answer would be 42240 people
