A square garden has a side of length that is 3 meters shorter than the length of a rectangle garden. Find the perimeter of the rectangle garden in terms of y.

square perimeter is 8y. rectangular side is 2y+1

If the square perimeter is 8y, then the square side would be:

square perimeter = 4*side

8y = 4*side

side=2y

The square garden side is 3m shorter than the length of the rectangle garden. The rectangle garden length will be:

rectangle length = square sides + 3

rectangle length = 2y+3

rectangle perimeter = 2 (rectangle length + rectangle side)

rectangle perimeter = 2 (2y+3 + 2y+1)

rectangle perimeter = 2 (4y+4)

rectangle perimeter = 8y + 8
