    P=2b+2c

    P=2 (7.7) + 2 (17.2)

    P=15.2+34.4

    P=49.6 millimeters

    Solutions

    We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle. The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 * (Side A + Side B).

    We have the side lengths 7.7 mm and 17.2 mm.

    Solve

    2 * (Side A + Side B)

    2 * (Side A (7.7) + Side B (17.2))

    = (7.7 x 2) + (17.2 x 2)

    = 49.6

    The perimeter is 49.6 mm².
