First, find the area of the hallway.

\(Area=length*width\)

\(A=90*7\)

\(A=630\)

Now you know there are 630 square feet to be cleaned. To find the amount of cleaning solution needed, multiply this number by 1/2.

\(Solution=area* \frac{1}{2}\)

\(S=630* \frac{1}{2}\)

\(S= \frac{630}{2}\)

\(S=315\)

Answer: 315 fluid ounces

\(90*7 = 630ft ^{2} \\ \\ 1/2 floz ->1 ft^{2} \\ \\ 630/2=315 \\\\\boxed{315}\)
