Theory:

To calculate the area of the rhombus:
  • Using the base and height.
  • Using the diagonals
Using the base and height: We multiply the base with height to get the area of a rhombus.

Area of rhombus =b×h square units.
Where '\(b\)' is denoted as base, and '\(h\)' is denoted as height.
 
 
Using the diagonals: We multiply both the diagonals, and then divide by \(2\) to get the area of a rhombus.

Area of rhombus =12d1×d2 square units.
Where '\(d\)' is denoted as diagonals.
