The area of a rectangle is the product of length and width.
   A = length*width

Jarel's garden has an area of
   A = (9 ft)*(3 ft) = 27 ft²

Morgan's garden has an area of
   A = (6 ft)*(6 ft) = 36 ft²

The difference in area of the two gardens is
   36 ft² - 27 ft² = 9 ft²


The appropriate choice is 
   B. 9 square feet
