Q. An airplane ticket is

10\,\text{centimeters}

long and

8\,\text{centimeters}

tall. 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 for length and width into the formula. $\newline$ $A = 10 \, \text{cm} \times 8 \, \text{cm}$
Perform Multiplication: Perform the multiplication to find the area. $A = 80$ square centimeters
Verify Calculation: Verify that the calculation is correct by checking the multiplication. $10$ times $8$ is indeed $80$ , so there is no math error.
