Area Calculator
This area calculator computes the area of a number of geometric shapes, including rectangle, square, triangle, parallelogram, circle, ellipse, sector, rhombus and trapezoid.
Calculation Steps
📌 Definition of Area
Area is the measure of the amount of space occupied by a two-dimensional surface or shape. It is expressed in square units such as square meters (m²) or square centimeters (cm²).
📌 Key Area Formulas
Area calculations vary depending on the shape:
- Square: A = side²
- Rectangle: A = length × width
- Triangle: A = ½ × base × height
- Circle: A = π × r²
📌 Examples of Area Calculation
| Shape | Formula | Example Calculation |
|---|---|---|
| Square (side = 4) | side² | 16 |
| Rectangle (5 × 3) | length × width | 15 |
| Circle (r = 3) | π × r² | 28.27 |
🔧 Practical Applications of Area Calculation
1. Architecture & Construction: Used for floor space planning and land measurement.
2. Agriculture: Helps calculate land area for farming and irrigation.
3. Interior Design: Essential for furniture placement and home layout optimization.
4. Science & Engineering: Applied in material science and surface treatment calculations.
❓ FAQs
Q1: How do I find the area of a rectangle?
✅ Use the formula A = length × width.
Q2: What units are used for measuring area?
✅ Common units include square meters (m²), square feet (ft²), and acres.
Q3: How is area different from perimeter?
✅ Area measures surface coverage, while perimeter measures the boundary length.
Q4: How do I calculate the area of an irregular shape?
✅ Divide it into standard shapes, calculate each area, and sum them.
Q5: Where is area calculation commonly used?
✅ In construction, land planning, architecture, and scientific research.
