Given:
A rectangular park is 5/6 miles wide and 1 5/7 miles long.
So, the length = 1 57/7 miles
And the width = 5/6 miles
The area of the rectangular park = length x width
[tex]Area=1\frac{5}{7}\times\frac{5}{6}=\frac{12}{7}\times\frac{5}{6}=\frac{10}{7}=1\frac{3}{7}\text{ }miles^2[/tex]So, the answer will be Area = 1 3/7 square miles
