Each side of the map covers 8 miles since it is a square and \(\sqrt(64)=8\).
Then we know that \(1in:\frac{4}{3}m = x = 8m\), so that 8 miles corresponds to 6 inches.
Thus, the perimeter is \(6*4 = 24\).
Answer D

Here it is about the SQUARE map.
So each side of the sq map =\(\sqrt{64}\)(in square, Area = side^2)
= 8 miles
Since \(1 inch =\frac{4}{3}\) miles,
Therefore \(8 miles=\frac{3}{4}*8= 6 inch\)
Therefore perimeter of square map in inch = 4*side = 4*6 =24 inch
