    Step-by-step explanation:

    If the square has an area of 49 ft^2, then the length of one of its sides is

    s = √ (49 ft^2) = 7 ft, and its perimeter is P = 4 (7 ft) = 28 ft.

    As for the rectangle: let W and L represent the width and length, respectively. Then W*L = 24 ft^2 is the area. L = W + 2 ft. Therefore,

    W (W + 2) = 24, or W^2 + 2W - 24 = 0, or (W + 6) (W - 4) = 0. Thus, W = 4 ft.

    The perimeter of this rectangle is P = 2W + 2L, or

    P = 2 (4 ft) + 2 (6 ft) = 24 ft.

    The square has the larger perimeter: It is 28 ft.
