Part A) 24.79 acres
1) Since that plot has an area of
[tex]1,089,000ft^2=1.08\times10^6ft^2[/tex]And the number of units must be between 10 and 10² units.
Part A)
[tex]\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}[/tex]2) Let's convert them to the apparently plausible units, see if it fits within the given interval.
[tex]\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}[/tex]We can see that 0.03 m² does not belong to the given interval.
3) Hence, the answer is 24.79 acres.
