Brilio.net – A rhombus is a flat, rectangular shape with four sides of the same length and two pairs of different angles. A rhombus is also a type of parallelogram. Before learning further about the area of a rhombus, you need to understand the characteristics of a rhombus.
By knowing the characteristics of a rhombus, you can more easily know the value of each diagonal and its base. Well, as for the characteristic feature of a rhombus that is easy to recognize, that is, it has four sides of equal length, it has two right-angled angles that are each the same size as the angle in front of it, it has two diagonals that are not the same length, and it has two folding symmetry and two rotational symmetries.
The area of a rhombus is a measure of the total area or plane that covers all parts of a rhombus-shaped flat shape. A rhombus is a four-sided flat shape with a shape similar to a diamond or rhombus. Opposite sides in a rhombus have the same length, and the angle between two consecutive sides is 90 degrees.

Immediately, here is the formula for the area of a rhombus along with its elements and example questions and discussion. Compiled by brilio.net from various sources on Thursday (7/9).
The formula for the area of a rhombus
To calculate the area of a rhombus, you can use several formulas, depending on the known values. For example, if in the problem the value of the diagonal length is known, it can be formulated as follows.

1. If the lengths of the two diagonals of the rhombus are known (d1 and d2), then the formula is used:
Area of Rhombus = (1/2) × d1 × d1 or L = 1/2 . d1. d2
Where:
– d1 is the length of the first diagonal.
– d2 is the length of the second diagonal.
2. If the length of the side of the rhombus (s) and the angle between the two diagonals (θ) are known, you can use the following formula:
Area of Rhombus = s² × sin(θ)
Where:
– s is the length of the side of the rhombus.
– θ is the angle between two diagonals in radians.
