Key points about a rhombus: 1. All sides of a rhombus are equal. 2. The diagonals bisect each other at right angles.
Steps to solve: 1. Use the Pythagoras theorem to find the side length of the rhombus. Each side is the hypotenuse of the right triangles formed by the diagonals. From the figure: - One half of diagonal CE is 5, and one half of diagonal RI is 12. - The side length (s) is given by:
Perimeter = 4 × side length = 4 × 13 = 52
