What is the perimeter of a rhombus-shaped highway sign with a 20-centimeter side

Respuesta :

10-06-2017

The measure of all 4 sides of a rhombus are equal so if one side is 20 cm, the other 3 are 20 cm as well. The perimeter is all of the sides added together, so 20 + 20 + 20 + 20 = 80

The perimeter is 80 cm.
