    60 inches

    Step-by-step explanation:

    In a rectangle, there are 2 pairs of congruent sides. Therefore, the perimeter of a rectangle can be found using:

    p=l+l+w+w

    We know that the length is 18 and the width is 12, so we can substitute 18 in for l, and 12 in for w.

    p=18+18+12+12

    Add all the numbers together

    p=60

    So, the perimeter is 60 inches
