The city of Yorkton, Saskatchewan, has an area of 24.0 km^2. If this city were a perfect square, what would it’s exact perimeter
Elis [28]

Answer:

8\sqrt{6}  inches

Step-by-step explanation:

Let l represent the length of the square

The area of a square = l^2

That means,

l^2 = 24 km^2

Take the square root of both sides

l = \sqrt{24}

l = \sqrt{4*6

l = \sqrt{4} *\sqrt{6}

l = 2\sqrt{6}

Now lets find the perimeter

Perimeter of a square, P = 4l

P = 4* 2\sqrt{6}

P = 8\sqrt{6} inches
