# Rhombus

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

#### Examples

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:
