Surface Area Formulas
Rectangle = L × W; Circle = πr²; Triangle = ½bh; Trapezoid = ½(a + b)h
Converts automatically into square feet, square meters, square yards, acres, and hectares.
Worked Example
Plot of 40 ft by 60 ft
Dimensions: 40 ft width, 60 ft length.
• Area = 40 × 60 = 2,400 sq ft
• Metric conversion = 222.97 sq meters (0.055 acres)
Total plot area is 2,400 sq ft (223 m²).
