On a square map one inch is equal to 4/3 miles. If the map covers 64 square miles, then what is the perimeter of the map in inches?

(A) 6 inches

(B) 8 inches

(C) 16 inches

(D) 24 inches

(E) 32 inches

Kudos for correct solution.

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
