A scale diagram of Marissa's backyard is shown above. Each square on the grid measures 1 cm on a side.
If the actual perimeter of Marissa's patio is 20 feet, what is the actual perimeter of her pool?
To find the actual perimeter of Marissa's pool, we first need to determine the scale factor between the grid and the actual measurements.
In the diagram, the patio has a perimeter of 12 squares, which means the actual perimeter is 12 cm. Since the scale is 1 cm on the diagram = 1 foot in real life, the actual perimeter of the patio is 12 feet.
Since the patio and pool are both rectangles with the same scale factor, the actual perimeter of the pool is also 12 feet.
Therefore, the actual perimeter of Marissa's pool is 12 feet.

My apologies for the error in my previous response.
In the diagram, the patio has a perimeter of 12 squares, which means the actual perimeter is 12 cm. Since 1 cm on the diagram represents 1 foot in real life, the actual perimeter of the patio is 12 feet.
The pool encloses an area that is 3 squares wide and 4 squares long. Therefore, the actual width is 3 feet and the actual length is 4 feet.
The actual perimeter of the pool can be calculated as:
Perimeter = 2(width) + 2(length)
Perimeter = 2(3 feet) + 2(4 feet)
Perimeter = 6 feet + 8 feet
Perimeter = 14 feet
Therefore, the actual perimeter of Marissa's pool is 14 feet.
