The area of a rhombus with length of diagonal as 24 inches and 36 inches is 432 in²

<h3>Rhombus</h3>

Rhombus is a quadrilateral with two pairs of opposite and equal parallel sides. All the sides of a rhombus are equal and the diagonals bisect each other at 90 degrees.

The area (A) of a rhombus is given by:

  • A = (pq) / 2

where p, q are the length of the diagonals.

Given that:

  • p = 24 in, q = 36 in, hence:
  • A = (24 * 36) / 2
  • A = 432 in²

The area of a rhombus with length of diagonal as 24 inches and 36 inches is 432 in²
