Front

What is the formula for calculating the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

If a rectangle has a length of 10 feet and a width of 9 feet, what is its perimeter?

If a rectangle has a length of 8 feet and a width of 4 feet, what is its area?

Back

The area is 32 square feet.

Front

What is the relationship between the perimeter and area of a square?

Back

The perimeter of a square is related to its area; the perimeter is 4 times the length of one side, while the area is the side length squared.
