fig.3


Length of diagonal AC is given by-




√(9 + 49)


= √58 units


Length of diagonal BD is given by-




= √(9 + 49)


= √58 units


Clearly, the length of the diagonals of the rectangle ABCD are equal.


Mid-point of Diagonal AC is given by




Similarly, Mid-point of Diagonal BD is given by




Clearly, the coordinates of mid-point of both the diagonals coincide i.e. diagonals of the rectangle bisect each other.
