Geometry Calculation Table
| Shape | Dimensions | Area Formula | Perimeter Formula |
|---|---|---|---|
| Rectangle | Length × Width | A = l × w | P = 2(l + w) |
| Circle | Radius | A = πr² | C = 2πr |
| Triangle | Three Sides | A = √[s(s-a)(s-b)(s-c)] | P = a + b + c |
| Square | Side Length | A = s² | P = 4s |
Frequently Asked Questions
What shapes can this calculator handle?
The calculator supports rectangles, squares, circles, triangles, trapezoids, and parallelograms with their respective area and perimeter calculations.
How accurate are the geometry calculations?
The calculator uses precise mathematical formulas including Heron's formula for triangles and standard geometric equations for accurate results.
What units can I use for measurements?
You can use any unit of measurement (inches, feet, meters, etc.). The calculator maintains unit consistency in results.
Can I calculate triangle area with three sides?
Yes! The calculator uses Heron's formula to calculate triangle area when you provide all three side lengths.
What additional properties are calculated?
Beyond area and perimeter, the calculator provides diagonals for rectangles/squares, diameter for circles, and semi-perimeter for triangles.
Is this suitable for construction projects?
Absolutely! This calculator is perfect for construction, architecture, landscaping, and any project requiring geometric calculations.
How do I calculate irregular shapes?
For irregular shapes, break them down into basic geometric shapes and calculate each section separately, then sum the results.
