To find the perimeter of Lorenzo's patio, you need to understand that perimeter is a measurement of distance around a sided figure.
We know the side lengths are 12 feet, 14 feet, 12 feet, and 14 feet because it is a rectangle.
Add all these together to find the total distance around.
12 + 12 + 14 + 14 or (12 x 2) + (14 x 2) = 52 feet
The perimeter of Lorenzo's patio is 52 feet.
