Area of Parallelogram Using Vectors Calculator
This calculator finds the area of a parallelogram formed by two vectors using vector cross-product formulas in 2D and 3D.
Vector A
Vector B
Formula:
2D Area = |Ax × By − Ay × Bx|
3D Area = |A × B| = √[(AyBz − AzBy)² + (AzBx − AxBz)² + (AxBy − AyBx)²]
In geometry, a parallelogram is a four‑sided shape where opposite sides are parallel and equal in length. Usually, we find its area using base and height. But when shapes are described using vectors, a different and more powerful method is used.
When two vectors start from the same point, they form a parallelogram. The area of that parallelogram can be calculated using the cross product of the vectors. This method is widely used in mathematics, physics, engineering, and computer graphics.
The Area of Parallelogram Using Vectors Calculator helps you find this area quickly without doing long vector calculations by hand.

What the Calculator Is
A Vector Geometry Area Tool
This calculator finds the area of a parallelogram formed by two vectors. The vectors can be in:
- 2D space (x, y)
- 3D space (x, y, z)
You only need to enter the components of both vectors. The calculator then applies the cross‑product formula and gives you the area instantly.
Why Vector Area Matters
Vector‑based area is important in:
- Physics (force and work)
- Engineering mechanics
- Linear algebra
- Computer graphics
- Motion and direction analysis
It helps measure the space formed by directional quantities.
How the Calculator Works
Step 1: Enter Vector A
Input the components of the first vector, such as:
A = (Ax, Ay) or A = (Ax, Ay, Az)
Step 2: Enter Vector B
Input the components of the second vector:
B = (Bx, By) or B = (Bx, By, Bz)
Step 3: Click Calculate
The calculator computes the cross product of the vectors.
Step 4: Get the Area
The magnitude of the cross product gives the parallelogram area.
Key Formulas Used
General Vector Formula
Area = |A × B|
2D Vector Formula
Area = |Ax × By − Ay × Bx|
3D Vector Formula
A × B = (Ay × Bz − Az × By, Az × Bx − Ax × Bz, Ax × By − Ay × Bx)
Area = √((Ay×Bz−Az×By)² + (Az×Bx−Ax×Bz)² + (Ax×By−Ay×Bx)²)
These formulas calculate the space enclosed by the two vectors.
Step‑by‑Step Examples
Example 1: 2D Vectors
Given:
A = (3, 2) B = (1, 4)
Step 1: Apply the formula
Area = |3 × 4 − 2 × 1|
Area = |12 − 2| = 10
Result:
The area is 10 square units.
Example 2: 3D Vectors
Given:
A = (2, 1, 3) B = (1, 4, 2)
Cross product:
A × B = (1×2 − 3×4, 3×1 − 2×2, 2×4 − 1×1)
A × B = (2 − 12, 3 − 4, 8 − 1)
A × B = (−10, −1, 7)
Area = √(100 + 1 + 49)
Area ≈ 12.25
The area is 12.25 square units.
