    Perimeter = 69.4 cm

    Area = 299.92 square cm

    Step-by-step explanation:

    Given:

    length of rectangle (l) = 18.4 cm

    Width of rectangle (w) = 16.3 cm

    a) Perimeter of rectangle

    = 2 (l + w)

    = 2 (18.4+16.3)

    = 2 * 34.7

    = 69.4 cm

    b) Area of rectangle = lw = 18.4*16.3 = 299.92 square cm
