4(5x-20)=-20
20x-80=-20
20x=60
x=3
Hey there! :D
A square has four sides.
The perimeter of something is all the sides added up.
So, we know that it would be 52 divided by 4.
52/4= 13
Each side is 13 meters long.
I hope this helps!

Answer:
Length of DE is 25.
Step-by-step explanation:
Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.
