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

[tex]A = a * b[/tex]

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the data we have to:

[tex]a = 21 \ feet\\b = 9 \ feet[/tex]

Replacing the data we have:

[tex]A = 21 * 9\\A = 189[/tex]

Finally, the floor area is [tex]189 \ ft ^ 2[/tex]

Answer:

[tex]189 \ ft ^ 2[/tex]
