Q. A bedroom door is

3

feet wide and

8

feet tall. What is its area?

\newline

\newline

\_\_\_\_

square feet

Calculate Area: To find the area of a rectangle, we multiply the width by the height. $\newline$ Area = Width $\times$ Height $\newline$ In this case, the width is $3$ feet and the height is $8$ feet. $\newline$ So, Area = $3$ feet $\times$ $8$ feet
Perform Multiplication: Now we perform the multiplication to find the area. $3 \text{ feet} \times 8 \text{ feet} = 24 \text{ square feet}$
