Work space

Every person in a conference room must have at least 36 square feet of workspace. A conference room is 28 by 20 ft. find the maximum number of people the room can accommodate.

Correct answer:

n =  15

Step-by-step explanation:

$$\begin{gathered} P=36{\text{ft}}^2 \\ a=28\text{ft} \\ b=20\text{ft} \\ S=a\cdot b=28\cdot 20=560{\text{ft}}^2 \\ {n}_0=S/P=560/36=\frac{140}{9}=15\frac{5}{9}\doteq 15.5556 \\ n=\lfloor n_0\rfloor =\lfloor 15.5556\rfloor =15 \end{gathered}$$
