Question 829257
How much AREA per HOURS?  Calculate the amount of area and the amount of hours, and form their ratio, and compute.


Area painted:  {{{(1/2)(6*9)=3*9=27* ft^2}}}


Time in hours:  {{{(1/5)*hour}}}


Painting rate:  {{{highlight_green((27/(1/5))*(ft^2/hour))=27*5=25*5+2*5=highlight(135*ft^2/hour)}}}
