Kite and Rhombus
A kite, or deltoid, is a quadrilateral with two disjoint pairs of congruent adjacent sides, in contrast to a parallelogram, where the sides of equal length are opposite.

RomboA Rhombus is a four-sided polygon having all four sides of equal length and whose opposite sides are parallel (every rhombus is a kite).

Each rhombus has two diagonals. The biggest one is called long diagonal and the smaller one is called short diagonal. (Note that the diagonals of a rhombus are perpendicular).

Area of kites and rhombuses

The area of any kite or rhombus is equal to one-half the product of the lengths D and d of its diagonals.

Find the area in cm2

A=60 cm2

Find the area of the rhombus where:

The lenght of one side is 5 units and the short diagonal is 6 units long.
