Parallelogram - area2

The Area of a Parallelogram calculator 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
