First find the areas of the walls       14 x 7      and    25 x7        (there are TWO of each of these walls)

 

Sum up the areas    you found above

 

 

Now DOUBLE this sum   (she wants TWO coats of paint)  = TOTAL SUM AREA

 

 

then

TOTAL SUM AREA / 500 ft2/gal    = # gallons required.....
