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
