### Area of Rhombus of side 355 and Geometric properties like symmetry,perimeter of rhombus,diagonals of rhombus Area of a rhombus with side 355 units and base angle 45 degrees = side x side x sine of baseAngle = 355 x 355 x 0.7071 = 89112.2775 square units Perimeter of a rhombus with side 355 units = 4 * side = 4 * 355 = 1420 units Length of the two Diagonals of a rhombus with side 355 units = 2 * length of side * sin(BaseAngle/2.0) and 2 * length of side *cos(BaseAngle/2.0) = 2 * 355 * sine of 22.5 degrees and 2 * 355 * cosine of 22.5 degrees = 271.71 and 655.95 units Height of the Rhombus = Area of Rhombus / (length of side) = 251.02 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.
