Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.
Anton [14]

Option C:

Area of the wall =94\frac{15}{16} square feet

Solution:

Length of the wall = 12 \frac{1}{4} feet

Width of the wall = 7 \frac{3}{4} feet

Area of the wall = length × width

                          $=12 \frac{1}{4}\times 7 \frac{3}{4}  

Convert mixed fraction into improper fraction.

                          $=\frac{12 \times 4+1}{4}\times  \frac{7\times 4+3}{4}

                          $=\frac{49}{4}\times  \frac{31}{4}

                          $=\frac{1519}{16}

Convert improper fraction into mixed fraction.

                          $=94\frac{15}{16}

Area of the wall =94\frac{15}{16} square feet

Option C is the correct answer.
