Alan = en×boy; çevre = 2(en+boy).

A=w×h

Example

5×3 = 15.

Guide

Rectangle area and perimeter from width and height for rooms, plots, or cut lists. Informational—not a cadastral survey.

Area and perimeter formulae

Area = width × height; perimeter = 2 × (width + height). Keep linear units consistent so area is squared.

2026 notes and common mistakes

Mixing cm and m, or treating net vs gross floor area as identical, skews material and rent estimates.

Tips

  • Measure both sides in the same unit.
  • For information only—add waste for materials.
