How to find the area of rhombus if the diagonals are given |
|
Answer» The area of a rhombus can be defined as the amount of space enclosed by a rhombus in a two-DIMENSIONAL space. To recall, a rhombus is a type of quadrilateral projected on a two dimensional (2D) plane, having four sides that are EQUAL in length and are congruent. It is also known as equilateral quadrilateral because all its four sides are equal in nature. Area of Rhombus Formula Different FORMULAS to find the area of a rhombus are: Formulas to Calculate Area of Rhombus Using Diagonals A = ½ × d1 × d2 Using Base and Height A = b × h Using Trigonometry A = B2 × Sin(a) Where, d1 = length of diagonal 1 d2 = length of diagonal 2 b = length of any side h = height of rhombus a = measure of any interior angle Area of Rhombus |
