    11 square bars of 1 x 1 can be made

    3 square bars of 3 x 3 can be cut

    12 (2 * 6) inches square is wasted if only 3 x 3 bars are served

    Step-by-step explanation:

    The bar produced will be 11 x 15 inch

    But we need 1 x 1 square bars so 11 x 15 / 1 x 1 = 11 square bars can be easily cut leaving out 4 inches on one side

    We also need 3 x 3 square bars so 11 x 15 / 3 x 3 = 3 square bars leaving out 2 inches on one side and 6 inches on the other side.

    12 (2 * 6) inches square is wasted if only 3 x 3 bars are served.

    This problem is solved using simple basics because if we use the square formula then we have to reshape the whole bar. But as it is already given that the main bar is of rectangular shape having 11 x 15 sides and the bars cut have to be square in shape.
