The **Area of a Triangle Area based on Two Sides and Angle** calculator computes the area of a triangle given the length of two sides **(b **&** c)** and the inscribed angle **(α)**.

**INSTRUCTIONS: **Choose units and enter the following:

**(α)**Angle between Two Sides**(b)**Length of Side**(c)**Length of other Side

**AREA (A):**The calculator returns the area in square meters (m²). However, this can be automatically converted to other area units (e.g. square feet) via the pull-down menu.

The formula for the area of a triangle based on the length of two sides and the angle between them is:

`A = 1/2*b*c*sin(α)`

where:

- A = Area of the triangle
- b = length of one side
- c = length of other side
- α = angle between them

- Area of a triangle base on the base and height
- Area of a triangle using two sides and the interior angle.
- Area of a triangle using two angles and the interior side.
- Area of a triangle using three known sides.
