Area of a Rectangle Formula
The area of a rectangle is its width times its height.
Area = Width * Height
Compute the size of something whose dimensions are 3 feet by 18 feet. For example, a 3x18 foot room, apartment, office, or yard. To get the area of a box, multiply the height by the width. This calculator also takes units into account and will show the result in inches², cm², ft², and m².
