A rhombus has four equal sides and equal opposite angles.
The diagonals of a rhombus are perpendicular and the bisectors of the angles.
Area of a Rhombus
The area of a rhombus is equal to the length of the larger diagonal multiplied by the smaller diagonal, divided by two.
Perimeter of a rhombus
Find the area and perimeter of a rhombus whose diagonals are 30 and 16 cm, and its side measures 17 cm.
Calculate the side of a rhombus, knowing that the diagonals are 30 and 16 cm.
By applying the Pythagorean theorem for one of the triangles, we obtain:
