What is the perimeter of the rhombus?
units

Respuesta :

mathmate
The length of DE=sqrt((1-4)^2+(4-0)^2)=sqrt(3^2+4^2)=5
In principle, a rhombus has four equal sides, so the perimeter is 4*5=20 (units)

However, to ensure there is no typo, it is advisable to calculate separately the length of each and every side.

Answer:

the answer is "20
