The Area of a Parallelogram calculator /attachments/e6cb7950-da27-11e2-8e97-bc764e04d25f/Parallelogramarea2-illustration.png computes the are of a parallelogram based on the measure of two sides (a and b) and the angle (θ) adjoining them.

INSTRUCTIONS: Choose units and enter the following:

(a) The length of side a
(b) The length of side b
(θ) The angle between side a and b

Parallelogram Area (A): The calculator returns the area (A) in square meters. However, this can be automatically converted to other area units via the pull-down menu.

The Math

The formula for the area of a parallelogram is:

A = a•b•sin(θ)

where:

A is the area of a parallelogram
a is the length of the side
b is the length of the base
θ is the angle between side a and b
