Tile Coverage and Area Calculations

What is the formula for calculating the area of a rectangular patio?

• Area = πr²

• Area = length + width

• Area = length × width

• Area = 2 × (length + width)

How much additional area should be added for simple patterns when calculating tile coverage?

• 5%

• 10%

• 15%

• 20%

What is the formula for calculating the total number of tiles needed, including waste factor?

• Total tiles needed = Area × (1 + waste factor)

• Total tiles needed = Area × waste factor

• Total tiles needed = Area + waste factor

• Total tiles needed = Area / waste factor
