In this mini-lesson, you'll learn the formula used for calculating area of a rhombus. It will be shared with the help of some examples and practice questions with solution, using multimedia explanations by the instructor.

Here we explain how to calculate the area of a rhombus. To get the area of a rhombus, you need first to draw a line segment (b) from one vertex to another vertex. Following this, draw a perpendicular line segment (h) from a third vertex to the base. The rhombus has now two created triangles, with base (b) and height (h). The area of rhombus will be sum of the area of these two triangles i.e. 2 x ½ x bh = bh.

If the diagonal lengths of a rhombus are*d*_{1} and *d* _{2}, then its area can be calculated by the formula: Area = ½ × *d*_{1} × *d*_{1}. For example, if diagonals of the rhombus are 10 cm and 15 cm, the area works out to: ½ × 10 × 15 = 75 cm^{2}.
