Rectangle Area Calculator

The area of a rectangle is simply length multiplied by width. A room measuring 4 m by 3.5 m has a floor area of 14 m² — the number you need for flooring, paint coverage or rent-per-square-meter comparisons.

For L-shaped or irregular spaces, split them into rectangles, compute each area, and add them up. To convert your result between metric and imperial units, use the square meters to square feet converter.
