In this lesson, we will look at the formula used to calculate the area of a rhombus. You will learn it 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.
(More text below video...)
(Continued from above)
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 1/2 x bh = bh.
If the lengths of the diagonals of a rhombus are d_{1} and d_{2},
then its area can be calculated by the formula: Area = 1/2 x d_{1} x d_{2}.
For example, if diagonals of the rhombus are 10 cm and 15 cm, the area works out
to: 1/2 x 10 x 15 = 75 cm^{2}.
