49 tiles because a square has the same length as it does breadth. The Area of a square is length times breadth, so if length eqauls seven then so does the breadth which means that the area will be 7x7 which eqauls 49.

81 tiles squared because if it's a square then it would be 9x9 which is 81

The sides of a square are all the same length whereas a rectangle has two pairs of sides of equal length.

Area of a square is length2. Therefore length is square root of 20 which is 4.47 inches

For a square, the length of each side is equal to the square root of the area. In this case, the square root of 36 is 6. So, each side measures six units.

Depends entirely on the length and width. If it's square then 40 feet, but otherwise just add the length and width and double your answer...

For accurate calculations, more information is needed. For a rough estimate, you can assume the field is approximately square, and take the square root of the area to get the length. Or you may want to assume a different side ratio - for example, 1.5:1 - and do the corresponding calculations. It won't make much difference if all you want is a rough estimate.
