in a rhombus, the diagonals are perpendicular , so if you divide each diagonal in half (where they intersect) than you get a right triangle with sides 3 4 and x. Use pythagorean theorum and that side is 5. Because all sides of a rhombus are congruent, each side is 5, so the perimeter is 20. Hope i helped!:)
