Katrina is fencing her yard, which is shaped as a rhombus. She used (5x + 1) meters of fencing material for one side and (7x - 11) meters for the adjacent side.
What is the perimeter of the yard?
My teacher told me to add up all of the sides since its the perimeter. How exactly would you do that?
Is that even the right way to figure out the answer?
Answers:
116 meters
124 meters
140 meters
168 meters

Okay, a rhombus has
sides of equal length.
So, 5x+1=7x-11.
So,11+1=7x-5x,
12=2x, x=6.
So one side is
(5*6)+1=31.
So perimeter=31*4=
124.
