The sidelength of a square is the square root of its area - in this case, 
yards. Its perimeter is therefore four times that, or 
yards. Multiply by 36 to convert to inches:

To find the perimeter of a square, we need to find the side lengths. We can find the side lengths from the diagonal by recalling that the diagonal of a square creates two 45/45/90 triangles.
A 45/45/90 triangle has the following side-length ratios: 
This means that if our hypotenuse is 
long, our other two sides will be 14 meters long
So our side-length is 14 meters, find the perimeter via the following

Draw yourself a picture for this problem. If you create a square out of two triangles, they meet at the diagonal of the square. Since, we know the triangles are equilateral, then all of the side lengths of the triangle and square are equal. Therefore, we just take the side length and add that four times.
