I tried to adapt the proof of Harcourts theorem given in this paper but without success. There are several formulas for the rhombus that have to do with its. The area is the product of these two or as a formula.
The area of a rhombus is the number of square units inside the polygon.
Area p q2. Sin angle sin 180 - angle Above we have listed the most common formulas for working out the area of a rhombus but there are others too. The area of a rhombus is the number of square units inside the polygon. You can use variations to calculate the area using heights and angles as well.
