600 square feet. Multiply length by width - the result is the area in square feet.
20 X 30 = 600 square feet.
600 square feet. Just multiply length by width - the answer is the square footage.
200 square feet
Divide the square footage by the width in feet. Example: 20 sq. ft roll of material is made up of 10 linear feet by 2 feet in width. 20 square feet divided by 2 feet wide equals 10 linear feet and 2 feet wide. For linear feet ask yourself how long is it. 100 sq. ft. 1 foot wide would be 100 linear feet long.
20 X 16 = 320, 320 square feet
400 square feet
Read your own question! The square footage is 20!
The square footage of the room is determined by the floor dimensions. So if you have a 12 x 20 room the square footage is 240 square feet.
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 20*12 = 240 square feet.
12*20 = 240 square feet.
20 X 30 = 600 square feet.
18 ft X 20 ft = 360 Square feet
20 ft * 500 ft = 10000 square feet. Rather a large room!
480sq
840 sqft
260 feet squared !
20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
