A boundary calculator helps you compute the exact measurements of various geometric shapes. Whether you’re laying out a garden, constructing a building, or designing a piece of art, knowing these measurements ensures your project fits perfectly within its designated space.
Formula of Boundary Calculator
Rectangle:
The perimeter of a rectangle is calculated by the formula: Perimeter = 2 * (Length + Width) where Length is the length of the rectangle and Width is the width of the rectangle.
Square:
The perimeter of a square can be determined with: Perimeter = 4 * Side where Side is the length of one of the square’s sides.
Circle:
To find the circumference of a circle, use: Circumference = 2 * π * Radius where π (pi) is approximately 3.14159, and Radius is the radius of the circle.
Triangle:
The perimeter of a triangle is: Perimeter = Side1 + Side2 + Side3 where Side1, Side2, and Side3 are the lengths of the triangle’s sides.
Regular Polygon:
For a regular polygon, the perimeter is calculated as: Perimeter = Number of sides * Length of one side where all sides are of equal length
Table of General Terms
| Term | Definition | Example Use |
|---|---|---|
| Perimeter | Total distance around the edge of a polygon. | Calculating fence length for a rectangular yard. |
| Circumference | Distance around the circular boundary. | Determining the length of material for a circular track. |
| Radius | Distance from the center of a circle to any point on its edge. | Used to calculate the circumference of a round swimming pool. |
| Side | Length of one side of a polygon. | Determining the amount of paint needed for each wall of a square room. |
| π (Pi) | Mathematical constant, approximately equal to 3.14159. | Used in calculating the circumference of circular objects. |

Examples of Boundary Calculator
- Rectangle:
- Example: You want to calculate the fencing required for a rectangular yard.
- Calculation: If the yard is 20 meters long and 15 meters wide, the perimeter would be calculated as follows:Perimeter=2×(20 m+15 m)=70 m
- Outcome: You will need 70 meters of fencing.
- Square:
- Example: Determining the material needed for a square patio.
- Calculation: If each side of the patio is 10 meters, the perimeter would be:Perimeter=4×10 m=40 m
- Outcome: You will need 40 meters of material.
- Circle:
- Example: Measuring the border for a circular flower bed.
- Calculation: If the radius of the flower bed is 5 meters, the circumference is calculated as:Circumference=2×π×5 m≈31.42 m
- Outcome: The border around the flower bed should be about 31.42 meters.
- Triangle:
- Example: Setting up a triangular sail for shade.
- Calculation: If the sides of the triangle are 8 meters, 6 meters, and 10 meters, the perimeter is:Perimeter=8 m+6 m+10 m=24 m
- Outcome: The total length of the edges of the sail will be 24 meters.
- Regular Polygon:
- Example: Designing a custom, multi-sided table.
- Calculation: If the table is a hexagon (6 sides) with each side measuring 1.5 meters, the perimeter is:Perimeter=6×1.5 m=9 m
- Outcome: You will need materials measuring a total of 9 meters to create the table edges.
Most Common FAQs
Accuracy in measurements starts with the correct setup of the measuring tools and verifying the unit of measurement
Yes, for irregular shapes, multiple simple shapes can be calculate separately and then combined for the total measurement.
