How to Calculate Rectangle Area
The area of a rectangle is simply length multiplied by width. This fundamental formula is used in construction, real estate, farming, and daily life.
Rectangle Area Formula
A = length × width
Where:
- A = Area
- l = Length
- w = Width
Step-by-Step:
- 1
Measure length and width
Ensure both measurements use the same unit.
- 2
Multiply
Multiply length by width to get area in square units.
Worked Examples:
Room floor
l: 12 ftw: 10 ft
Result: 120 sq ft
A = 12 × 10 = 120 sq ft
