For this case we have that the area of the rectangle is given by:


A = a * b

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the data we have to:


a = 21 \ feet\\b = 9 \ feet

Replacing the data we have:


A = 21 * 9\\A = 189

Finally, the floor area is
189 \ ft ^ 2

Answer:


189 \ ft ^ 2
