c. 143
d. 15113⁄48

Answer 1

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

`A= \text{Length} * \text{width} \\ A=13.25 * 11.42\\ \\ A=151.3 \text{ square feet}\\ A\approx 151 \text{ square feet}\\`

a is the correct option.
