Question

a science fair poster is a rectangle 48 inches long and 24 inches wide. what is the area of the poster in square feet? be sure to include the correct unit in your answer.

Explanation:

Step1: Convert inches to feet

Since \(1\) foot \( = 12\) inches.
Length: \(l=\frac{48}{12}=4\) feet.
Width: \(w = \frac{24}{12}=2\) feet.

Step2: Calculate the area of the rectangle

The area formula for a rectangle is \(A=l\times w\).
Substitute \(l = 4\) and \(w = 2\) into the formula: \(A=4\times2\).

Answer:

\(8\ \text{ft}^2\)
