One acre of land is equal to 4046.86 sq.m. To know how far they can throw the ball from corner to corner can be interpreted in two ways: throwing the ball diagonally across the field or throwing the ball horizontally across the field. For the first question, since the field is a square, you can use the equation Diagonal of Square = A x sq.root of 2.
In this case, the answer would be 89.97 m. If the ball is thrown horizontally across the field, then you would only need to know the length of one side of the square, which is the square root of the area. Doing this would give you the answer 63.61 m.
43,560 square feet is equal to one acre If the land is a square (where the length would be equal to width), it is 208.71 ft by 208.71 ft in the meantime 208.71 x 208.71 = 43,560 If the land is rectangular, you would need to distinguish the length of one of the sides in order to know the length of the other side.
