Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around it, calculated by adding the lengths of all four sides. For a rectangle with length (l) and width (w), the formula is: Perimeter = 2(l + w).

Front

What is the area of a rectangle?

Back

The area of a rectangle is the amount of space inside it, calculated by multiplying the length (l) by the width (w). The formula is: Area = l × w.
