If the figures you are working to are exact them multiply the 2 together

20 x 16 = 320 sqft.

If there is a slight difference say extra inches length = 20ft 4inches and width = 16ft 10 inches then do the following.

Convert to inches length = 244 inches ( 20 x 12 + 4")
Width = 202 inches (16 x 12 + 10")

Now multiple the 2 numbers to gether then divide by 144. The reason you devide by 144 is that this is a sqft (ie 12" x 12" = 144").

so the answer would be 244 x 202 = 49,288 inches Divided by 144 = 342.277 sq ft.
