Question

bruno uses a piece of wrapping paper with dimensions ( 1\frac{1}{4} ) feet by 3 feet to wrap a gift. what is the total area of the paper used to wrap the gift? (\bigcirc \frac{1}{4}) square feet (\bigcirc \frac{3}{4}) square feet (\bigcirc 3\frac{1}{4}) square feet (\bigcirc 3\frac{3}{4}) square feet

Explanation:

Step1: Convert mixed number to improper fraction

The length is \(1\frac{1}{4}\) feet. Convert it to an improper fraction: \(1\frac{1}{4}=\frac{1\times4 + 1}{4}=\frac{5}{4}\) feet.

Step2: Calculate the area

The area of a rectangle is \(A = \text{length}\times\text{width}\). Here, length is \(\frac{5}{4}\) feet and width is 3 feet. So, \(A=\frac{5}{4}\times3=\frac{15}{4}\).

Step3: Convert improper fraction to mixed number

Convert \(\frac{15}{4}\) to a mixed number: \(\frac{15}{4}=3\frac{3}{4}\) square feet.

Answer:

\(3\frac{3}{4}\) square feet (the option: \(3\frac{3}{4}\) square feet)
