To find square feet means to find out the area of the room. Your room appears to be rectangular from the dimensions. Therefore, to find the area of the room, we will use the following formula:
Area = Length x Width
Area = 20 x 16
Area = 320 square feet
Therefore, the square footage of your room is 320 square feet or 320 feet2.
Area = Length x Width
Area = 20 x 16
Area = 320 square feet
Therefore, the square footage of your room is 320 square feet or 320 feet2.
