    To find the paremeter of a rectangle you need to add up all 4 sides.

    So in this case it will be 40.7 + 30.8 + 40.7 + 30.8 = 143 inches

    **Remember the two opposite sides of a rectangle are equal**

    to find the parameter you add all sides since the opposite are equal you can multiply 40.7 x 2 =81.4 and 30.8 x 2 = 61.6 add them together and you have 143
