The answer is: "10 cm" .

Method 1)
____________________________________________
2L + 2w = 40 ; Since the formula for perimeter of a rectangle (Note: a square is a rectangle) is:
P = 2L + 2w ; Note: L = length; w = width; P = perimeter;
______________________________________________________
Factor out a "2":
_________________
" 2L + 2w = 40" ;
2 (L+ w) = 40;
Divide each side of the question by "2" ;
____________________________________
[2 (L + w)] / 2 = 40 / 2 ;
____________________________________
to get: (L + w) = 20 ;
Note: this "rectangle is a square" ; so L= w".
__________________
20 /2 = 10 ;
L + w = 10 + 10 = 20.
This is a square, so each side of the square is the same length.
Each side is: 10 cm .

Method 2)
______________________________________________
We are given: The perimeter (sum of the lengths of all sides) of a square is "40 cm." Since a square has 4 sides of equal length:
Each side is: 40 cm / 4 = 10 cm.

Answer:
c -13
Step-by-step explanation:
The slope is 5/1. This is because it goes up 5 units and right one unit. This corresponds with the fact that slope is the rise/run on a line.
