Area of Rhombus
Area of Rhombus
Rhombus: quadrilateral all of whose sides have the same length.
Area of A Rhombus: A rhombus is actually just a special type of parallelogram. The "base times height" method: First pick one side to be the base. Any one will do, they are all the same length. Then determine the altitude - the perpendicular distance from the chosen base to the opposite side. The area is the product of these two, or, as a formula: Area = base x height:.
The "diagonals" method: Another simple formula for the area of a rhombus when you know the lengths of the diagonals. The area is half the product of the diagonals. As a formula: Area = where, d1 is the length of a diagonal and d2 is the length of the other diagonal

Example: Find the area of a rhombus having each side equal to 13 cm and one of whose deiagonals is 24 cm. Solution : Let ABCD be the given parallelogram whose diagonals intersect at O. We have, AB = 13 cm and AC = 24 cm. Since the diagonals of a rhombus bisect each other at right angles. Therefore, Using Pythagoras theorem, in Hence, OB = 5 cm Also, BD = 2 x OB = 10cm Hence , Area of rhombus ABCD = |

The experience was nice. I studied here for three years and saw a tremendous change in myself. I started liking subjects like English and SST which earlier I ran from. Extra knowledge gave me confidence to overcome competitive exams. One of the best institutes for secondary education.
