What is the perimeter of a rectangle with a length of 9 - 2y and width of 7?

32-4y

Step-by-step explanation:

2 (9-2y) + 2 (7) = 18-4y+14=32-4y

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
