to get the area of any thing you multiply the length by the width. (ex... 10x13= 1302feet) and that's how you tell the area of something
all you have to do to find the area of some thing is multiply the width by the length.
it is just that easy any one could do it.
it is 11.4 feet :) hope that helped, elly.

Edit:Square footage of the house's floor space (ie - an "1150 sq ft house") is not enough information. First you need to determine the square footage of the wall surface and any other surfaces you are going to paint (walls, trim, windows, etc..):(BTW the single cans of paint I deal with only cover 400 square feet of wall space, not 800! So check your paint can and adjust the math accordingly)Original answer:one gallon will cover 800 square feet of wall space. Consider this; are you covering a light color with a dark color or vice versa. Dark colors tend to take at least 2 coats.Here is a formula:Add together the length of each wall.[wall] + [wall]+ [wall] +[wall] = wall length For example, 16 + 16 + 20 + 20 = 72 feet.Multiply the total length of walls by the total height.72 feet x 9 feet = 648 square feetSubtract 20 square feet per door and 15 square feet per window.[wall] - [door]- [window] = square footage For example, 648 - 20 - 20 - 20 - 15 - 15 - 15 - 15 = 528 square feet.Divide the answer by 350 (the estimated coverage/gallon) for smooth walls; or divide by 300 for rough or textured walls, which soak up more paint.[square footage] ÷ 350 = 1.5 gallons for smooth walls per coat For example, 528 ÷ 350 = 1.5 gallons for smooth walls and 528 ÷ 300 = 1.76 gallons for rough/textured walls.Add 10 percent for waste.1.428 x .10 = 0.1428 1.428 + 0.1428 = 1.57or 2 gallons for each coat of paint. Between paint drying in the pan and mistakes along the way, you'll want to have this 10 percent cushion. After all, you don't want to run out.

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.
Read your own question! The square footage is 20!
two hundred and forty 12 x 20 = 240
400
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.
To get the square footage you simply multiply the length times the width. This means your room has a total of 320 sq ft. (floor space). This is the measurement for one plane (the floor), not the entire volume of the room.
240 square feet. Multiply the length by the width. The result is the area in square feet.
420
400 square feet
if you want the square footage, 15 ft x 20 ft is 300 square feet
