Question

a rectangular window is 48 in long and 36 in wide. jenny would like to buy a screen for the window. the cost of the screen is based on the number of square feet the screen is. use the facts to find the area of the window in square feet. conversion facts for length 1 foot (ft) = 12 inches (in) 1 yard (yd) = 3 feet (ft) 1 yard (yd) = 36 inches (in)

Explanation:

Step1: Convert length from inches to feet

Since \(1\) foot \( = 12\) inches, for length \(l = 48\) inches, \(l=\frac{48}{12}=4\) feet.

Step2: Convert width from inches to feet

Since \(1\) foot \( = 12\) inches, for width \(w = 36\) inches, \(w=\frac{36}{12}=3\) feet.

Step3: Calculate the area of the rectangle

The area formula for a rectangle is \(A=l\times w\). Substituting \(l = 4\) feet and \(w = 3\) feet, we get \(A=4\times3 = 12\) square feet.

Answer:

\(12\)
