Rectangular plot formula

Area = Length × Width. If both dimensions are in metres, the result is m²; if both are in feet, the result is sq ft.

Worked example

A 40 ft × 60 ft plot has 2,400 sq ft. Dividing by 10.7639 gives approximately 222.97 m².

How to use the calculator

Enter the rectangular length and width, then review the area and unit conversions.

Where it is useful

Preliminary building planning, site estimates, landscaping and educational calculations.

Important limitation

Irregular property boundaries should be measured using appropriate survey methods and official records.
