### Area of Rhombus of side 204 and Geometric properties like symmetry,perimeter of rhombus,diagonals of rhombus Area of a rhombus with side 204 units and base angle 30 degrees = side x side x sine of baseAngle = 204 x 204 x 0.5 = 20808.0 square units Perimeter of a rhombus with side 204 units = 4 * side = 4 * 204 = 816 units Length of the two Diagonals of a rhombus with side 204 units = 2 * length of side * sin(BaseAngle/2.0) and 2 * length of side *cos(BaseAngle/2.0) = 2 * 204 * sine of 15.0 degrees and 2 * 204 * cosine of 15.0 degrees = 105.6 and 394.1 units Height of the Rhombus = Area of Rhombus / (length of side) = 102.0 units The order of symmetry of a rhombus is 2 (number of times the shape co-incides with itself during a 360 degree rotation). The symmetry group is dihedral. And it is isotoxal or edge-transitive in nature, though these are concepts and details which some of you might encounter later. The number of axes of symmetry of a rhombus is 2: the two diagonals In general, there are multiple formulas to compute the area of rhombus. Depending on information available you may use either of them. Area of a rhombus = (square of side) x sine(base Angle) = product of diagonals/2 = base x height To understand more about the geometric features and properties of a rhombus, formulas related to mensuration etc. you might find it useful to read the properties of a Rhombus tutorial over here.
