The diagonals of a rhombus are perpendicular and the sides are equal. The diagonals bisect each other.
Therefore, there are 15-20-x triangles where x is the side length and the hypotenuse.
15^2+20^2=x^2=625
x=25 inches. Perimeter is 100 inches (4*25)ANSWER
This is a 15-20-25 triangle, which is a multiple of 5 of a 3-4-5 triangle.
