Variables Used
Cos (B/2) - Cos (B/2) is the value of the trigonometric cosine function of half of the given angle B of the triangle.
Area of Triangle - (Measured in Square Meter) - The Area of Triangle is the amount of region or space occupied by the Triangle.
Side A of Triangle - (Measured in Meter) - The Side A of Triangle is the length of the side A, of the three sides of the triangle. In other words, the side A of the Triangle is the side opposite to the angle A.
Side C of Triangle - (Measured in Meter) - The Side C of Triangle is the length of the side C of the three sides. In other words, side C of the Triangle is the side opposite to angle C.
Sin (B/2) - Sin (B/2) is the value of the trigonometric sine function of half of the given angle A of the triangle.
STEP 1: Convert Input(s) to Base Unit
Area of Triangle: 65 Square Meter --> 65 Square Meter No Conversion Required

## What is a Triangle?

The Triangle is the type of polygon, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
