    The perimeter of the rectangle is 32 - 4y

    Step-by-step explanation:

    To find the perimeter, we will simply follow the steps below;

    First write down the formula for finding the perimeter of a rectangle

    The formula for finding perimeter in a rectangle is;

    perimeter = 2l + 2w

    where l = length of the rectangle and w is equal to width of the rectangle

    From the question given, length = 9 - 2y and width = 7

    We can now proceed to insert the values into the formula;

    perimeter = 2l + 2w

    =2 (9-2y) + 2 (7)

    Then we will now simplify

    perimeter = 2 (9-2y) + 2 (7)

    =18 - 4y + 14

    = 18 + 14 - 4y

    =32 - 4y

    Therefore, the perimeter of the rectangle is 32 - 4y
