The map uses scale ratios to represent actual distance.
From the diagram (see attachment), we have:
[tex]\mathbf{Length = 2.5\ in}[/tex]
[tex]\mathbf{Width = 4\ in}[/tex]
The scale ratio is given as:
[tex]\mathbf{Scale : Actual = 1 in: 200ft}[/tex]
So, the actual length is:
[tex]\mathbf{Length = 2.5 \times 200ft}[/tex]
[tex]\mathbf{Length = 500ft}[/tex]
And the actual width is:
[tex]\mathbf{Width = 4 \times 200ft}[/tex]
[tex]\mathbf{Width = 800ft}[/tex]
Hence, the actual side lengths of the Lafayette Square is 500ft by 800ft
Recall that:
[tex]\mathbf{Scale : Actual = 1 in: 200ft}[/tex]
This means that:
1 inch represents 200 feet on the map
