First, find the area of the hallway.

[tex]Area=length*width[/tex]

[tex]A=90*7[/tex]

[tex]A=630[/tex]

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.

[tex]Solution=area* \frac{1}{2} [/tex]

[tex]S=630* \frac{1}{2} [/tex]

[tex]S= \frac{630}{2} [/tex]

[tex]S=315[/tex]

Answer: 315 fluid ounces
