How it works
Area of a rectangle = length × width. We always show both metric and imperial because UK trades quote in both.
Worked example
5 m × 4 m = 20 m² = 215.28 ft². Flooring at £25/m² = £500.
Who should use this
- •Estimating flooring, paint, tiles, turf
- •Comparing room sizes
Common mistakes
- ×Mixing metres and feet in the same calculation
- ×Forgetting to add 10% for cuts and waste on flooring
