Answer:
Step-by-step explanation:
The distance around the lot is the perimeter of the lot, which has a formula:
P 2L + 2W
We can fill in using the info given:
[tex]P=2(\frac{9}{8})+2(\frac{9}{10})[/tex] which multiplies to
[tex]P=\frac{18}{8}+\frac{18}{10}[/tex] and finding a common denominator:
[tex]P=\frac{90}{40}+\frac{72}{40}[/tex] and adding, gives you
[tex]P=\frac{162}{40}=4.05mi[/tex]
