Q. A bookmark is

7

centimeters tall and

3

centimeters wide. What is its area?

\newline

\_\_\_\_

square centimeters

Identify Formula: Identify the formula for the area of a rectangle. $\newline$ The formula for the area of a rectangle is $A = \text{length} \times \text{width}.$
Plug in Values: Plug in the values of length and width into the formula. $\newline$ $A = \text{length} \times \text{width}$ $\newline$ Replace length with $7 \, \text{cm}$ and width with $3 \, \text{cm}$ . $\newline$ $A = 7 \, \text{cm} \times 3 \, \text{cm}$
Perform Multiplication: Perform the multiplication to find the area. $\newline$ $A = 7 \, \text{cm} \times 3 \, \text{cm}$ $\newline$ $A = 21 \, \text{cm}^2$
State Final Answer: State the final answer. $\newline$ The area of the bookmark is $21$ square centimeters.
