- Calculating paint coverage for walls
- Real estate property area calculation
- Planning furniture arrangements and space utilization
Frequently Asked Questions
How do I calculate square footage of an L-shaped room?
Divide the L-shape into two rectangles. Calculate the area of each rectangle (length × width), then add them together. Example: Rectangle 1 is 10×12 ft (120 sq ft) and Rectangle 2 is 8×6 ft (48 sq ft): total = 168 sq ft.
How many square feet of paint do I need?
One gallon of paint typically covers 350–400 sq ft with one coat. Measure each wall's width × height, add them together, subtract windows and doors (~21 sq ft each), then divide by coverage rate. Always buy 10% extra.
