The area(S) of a rectangle can be calculated as

where
length of rectangle
and width of rectangle
For this solution, the known variables are:



Since the area (S) is known, the side of a length can be calculated as-


Solve for by dividing both sides by :
%7D%7B20%7D)
%7D%7B%5Ccancel%7B20%7D%7D)
)
Since the width is in miles, we need to convert miles to feet. We know that one mile is equal to feet, we will convert miles (width) to feet:
