Question

What is the perimeter of a rhombus?

Answer 1

the perimeter of a rhombus is 4a, where a is the side of a rhombus

Answer 2

First, all four sides of a rhombus are congruent, meaning that if we find one side, we can simply multiply by four to find the perimeter. Second, the diagonals of a rhombus are perpendicular bisectors of each other, thus giving us four right triangles and splitting each diagonal in half.
