- How do I calculate the area of a rectangle?
- Multiply the length by the width: Area = Length × Width. For example, a room 5 m long and 4 m wide has an area of 20 m².
- How do I calculate the area of a circle?
- Use the formula Area = π × r², where r is the radius. For a circle with radius 3 m: Area = 3.14159 × 9 = 28.27 m².
- What is the formula for the area of a triangle?
- Area = ½ × Base × Height. For a triangle with base 6 m and height 4 m: Area = 0.5 × 6 × 4 = 12 m².
- How do I calculate the area of a trapezoid?
- Area = ½ × (Base1 + Base2) × Height. For top 3 m, bottom 5 m, height 4 m: Area = 0.5 × (3 + 5) × 4 = 16 m².
- How do I calculate the area of an ellipse?
- Area = π × a × b, where a and b are the semi-axes. For a = 4 m and b = 2 m: Area = 3.14159 × 4 × 2 = 25.13 m².
- How do I convert square meters to square feet?
- Multiply square meters by 10.764. For example, 20 m² = 20 × 10.764 = 215.28 ft².
- How many square feet in a square meter?
- One square meter equals exactly 10.764 square feet. Conversely, 1 ft² = 0.0929 m².
- How do I calculate how much flooring I need?
- Measure the room area in m², then add 10% for cuts and waste. A 20 m² room needs approximately 22 m² of flooring material.
- How do I add 10% waste for flooring installation?
- Multiply the calculated area by 1.10. For example, 20 m² × 1.10 = 22 m². This extra material covers cuts, defects, and future repairs.
- How do I calculate the area of an L-shaped room?
- Divide the L-shape into two rectangles, calculate the area of each, then add them together. For example, 4×3 m + 3×2 m = 12 + 6 = 18 m².
- How do I calculate wall area for painting?
- Measure each wall (width × height), add them up, then subtract door and window areas. Add 10–15% for coverage overlap. Typical paint covers 10–12 m² per litre.
- How do I calculate garden or lawn area?
- For rectangular gardens: Length × Width. For irregular shapes, divide into triangles and rectangles, calculate each, then sum. Use satellite maps for large plots.
- What is the difference between area and perimeter?
- Area is the 2D space inside a shape (measured in m² or ft²). Perimeter is the total length of the shape's boundary (measured in m or ft). Both are shown by this calculator.
- How do I calculate the area of a land plot?
- For rectangular plots: Length × Width. For irregular plots, divide into triangles using the shoelace formula or use GPS survey tools. 1 hectare = 10,000 m².
- How many square meters in an acre / hectare?
- 1 hectare = 10,000 m². 1 acre = 4,047 m². 1 are = 100 m². So 2.5 acres ≈ 10,117 m² ≈ 1.01 hectares.
