What is the perimeter of a rectangle measuring 5 cm by 7 cm?

Explanation:
Finding the perimeter of a rectangle is about summing all four sides. Opposite sides are equal, so you can add the lengths four times: 5 cm + 7 cm + 5 cm + 7 cm = 24 cm. Using the formula P = 2(length + width) gives P = 2(5 + 7) = 24 cm. Therefore, the perimeter is 24 cm.
