Q. The area of a rectangular portrait is

18

square feet. The portrait is

3

feet wide. How high is it?

\newline

\newline

\_\_\_\_

feet

Identify formula: Step $1$ : Identify the formula to find the height of the rectangle. $\newline$ Area of a rectangle = $\text{Width} \times \text{Height}$ . $\newline$ To find the Height, rearrange the formula: $\text{Height} = \frac{\text{Area}}{\text{Width}}$ . $\newline$ Calculation: $\text{Height} = \frac{18 \, \text{sq ft}}{3 \, \text{ft}}$ .
Perform division: Step $2$ : Perform the division to find the height. $\newline$ $18 \div 3 = 6$ . $\newline$ So, the height of the portrait is $6$ feet.
