We have The floor in the tool room measures 13 feet 3 inches by 11 feet 5 inches.
Let us convert inches to feet since we want the area in square feet.
We know that 1 inch = 0.0833333 feet .
Therefore, we have
3 inches = 0.25 feet
5 inches = 0.42 feet
Thus, we have the below dimension in feet
Length = 13 feet 3 inches = 13+0.25 = 13.25 feet
Width = 11 feet 5 inches = 11+0.42 = 11.42 feet
Hence, area of the room is given by
[tex]A= \text{Length} \times \text{width} \\ A=13.25 \times 11.42\\ \\ A=151.3 \text{ square feet}\\ A\approx 151 \text{ square feet}\\[/tex]
a is the correct option.
