How do you find the area of a rhombus?

Answer 1

Area = base x height.

This formula also works for parallelograms, rectangles and squares.
You find the area of a rhombus by multiplying l times h (length times height) where the height means the perpendicular distance from one side of length l to the other side.
There are three ways to find the area of a rhombus, but these two ways are the easiest.

• You can use A = ba (base times altitude/height)
• You can use A= 1/2(d1d2) (1 half or 0.5 times diagonal 1 times diagonal 2)

The third option is s^2*sin(A) where s is the side length and A is an angle. It all depends on what information you are given.
Area of Rhombus = length of first diagonal x length of second diagonal / 2

Answer 2

The answer depends on what information you have about the rhombus. Some examples:

• Length of any side (b) and height or the perpendicular distance between a pair of parallel sides (h): b*h
  
• Length of any side (b) and any one angle (A) : b^2*sin(A)
  
• Length of diagonals (c, and d): c*d
