This article shows how calculate the area of a rhombus, which is a shape with four equal sides. A square is a rhombus, but a rhombus does not have to be a square. There are several ways to get the area of the rhombus, depending on what you know about it and if you continue reading you will be able to learn various formulas that will help you take the area of the rhombus.
Diagonals
You can calculate the area of a rhombus if you know the length of the diagonals, which are lines connecting opposite corners. The area of a rhombus is one diagonal multiplied by another diagonal, divided by 2.
Example: If one diagonal is 3, and another diagonal is 4, 3 x 4 = 12, and 12/2 = 6.
Thus, the area is 6.
Base and height
If you know the length of either side of the rhombus and the height, which is the shortest distance between either side and the opposite side, you can calculate the area of the rhombus. Just find the length of one side and multiply it by the height.
The formula is:
Side and angle
If you know any side and any angle of the rhombus, you can use the trigonometric method. For this method you must use a scientific calculator with trigonometric functions (sine, cosine, tangent).
The area of the rhombus is the side squared (or side by side), multiplied by the sine of the angle. No matter what angle, they both have the same sine because they both add up to 180.
The formula is:
