11'9x21' equal how many square feet?

Answer 1

To determine how many square feet a rectangular area is, you multiply the length by the width. For these two particular values, first convert 9" (from the value 11'9) into a decimal value:

9/12 = 0.75"

Therefore, 11'9 = 11.75'.

Then calculate:

Area = 11.75 x 21

Area = 246.75 ft^2

Answer 2

For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 246.75 square feet.

Answer 3

246.75 square feet.
