Perimeter of a Quadrilateral Calculator

How to use the Perimeter of a Quadrilateral Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

trapezoid = trapA + trapB + trapC + trapD

trapA1 =sqrt( (x2 - x1)^2 + (y2 - y1)^2)

trapB1 = sqrt( (x4 - x1)^2 + (y4 - y1)^2)

trapC1 = sqrt( (x3 - x2)^2 + (y3 - y2)^2)

trapD1 = sqrt( (x4 - x3)^2 + (y4 - y3)^2)

parallelogram = trapA1+trapB1+trapC1+trapD1

Frequently asked questions

What is the perimeter of a quadrilateral?

The perimeter of a quadrilateral is the total length of all its sides. It is calculated by adding together the lengths of each of the four sides. For example, if a quadrilateral has sides of lengths a, b, c, and d, the perimeter (P) is given by the formula: P = a + b + c + d.

How do I use a perimeter of a quadrilateral calculator?

To use a perimeter calculator, simply input the lengths of the four sides of your quadrilateral into the designated fields. The calculator will automatically compute the perimeter and display the result. Some calculators may also accommodate input for different types of quadrilaterals such as rectangles or squares.

Can the perimeter calculator handle irregular quadrilaterals?

Yes, most perimeter calculators can easily handle irregular quadrilaterals. Simply enter the specific lengths of each side regardless of their arrangement, and the calculator will provide you with the total perimeter.

What if I only know the coordinates of the vertices?

If you have the coordinates of the vertices of a quadrilateral, you can still calculate the perimeter. Most calculators offer an option to input coordinates, which will then compute the distance between each pair of vertices. The total of these distances will give you the perimeter.

Are there different types of quadrilaterals?

Yes, there are several types of quadrilaterals including squares, rectangles, rhombuses, trapezoids, and parallelograms. Each type may have specific properties related to their sides and angles, but the perimeter calculation remains consistent across all quadrilaterals.
