    Multiple both numbers by 2 since there are 2 of them on a rectangle. After, add them.

    30 x 2 = 60

    39 x 2 = 78

    60 + 78 = 138

    And never forget to label your units!

    The perimeter of the rectangle is 138 inches.

    To get the area, multiply the sides by each other.

    30 x 39 = 1170

    The area of the rectangle is 1170 inches^2, or 1170 inches squared.
