    Perimeter is the sum of all the lengths of the sides of the rectangle. Rectangles have two sets of parallel sides, each pair being the same length.
    So to find the perimeter: 2(6 5/7) + 2(2 5/6) can be used

    Since the question is in fraction form, I will work through the problem and provide an answer in fraction form as well.

    6 and 5/7 as an improper fraction is 47/7. 2 and 5/6 as an improper fraction is 17/6. So our new equation is:

    2(47/7) + 2(17/6)

    After multiplying both fractions by 2, we get:

    94/7 + 34/6

    In order to add we must find the least common denominator, which is 42

    After converting our fractions and using the LCD, the equation is:

    564/42 + 238/42

    Adding these together results in 802/42

    Simplifying the fraction results in 19 4/42, or 19 2/21
