    Here is the set up:

    We know the given dimensions are increased by the same number.

    Let x be that number.

    The garden is a rectangle.

    Area = length times width.

    5m = 5 meters

    12m = 12 meters

    Area is 120 meters^2.

    Here is your equation:

    120 = (5 + x) (12 + x)

    Take it from here.
