600 sq.ft.

Step-by-step explanation:

10 * 24 = 240 / 2 = 120

20*24 = 480

480+120 = 600

600 sq.ft.

Becaues 63 employees is 90% of the total amount, we can set up this equation because 90% is the same as 0.9.  I am setting the total amount of employees equal to x.

x*0.9 = 63

Now, we solve for x.  We do this by dividing both sides by 0.9.

x = 70

So, there is a total of 70 employees at Stalling Printing.
