Calculation of the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, you need to know the length and width of the rectangle. In this case, the length of the rectangle is 7 cm and the width is 2 cm.

The formula to calculate the perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

Substituting the given values into the formula, we get:

Perimeter = 2 * (7 + 2)

Simplifying the equation, we have:

Perimeter = 2 * 9

Therefore, the perimeter of the rectangle is 18 cm.
