Option C:
Area of the wall [tex]=94\frac{15}{16}[/tex] square feet
Solution:
Length of the wall = [tex]12 \frac{1}{4}[/tex] feet
Width of the wall = [tex]7 \frac{3}{4}[/tex] feet
Area of the wall = length × width
[tex]$=12 \frac{1}{4}\times 7 \frac{3}{4}[/tex]
Convert mixed fraction into improper fraction.
[tex]$=\frac{12 \times 4+1}{4}\times \frac{7\times 4+3}{4}[/tex]
[tex]$=\frac{49}{4}\times \frac{31}{4}[/tex]
[tex]$=\frac{1519}{16}[/tex]
Convert improper fraction into mixed fraction.
[tex]$=94\frac{15}{16}[/tex]
Area of the wall [tex]=94\frac{15}{16}[/tex] square feet
Option C is the correct answer.
