A square has four sides which all have the same length.
So if we call the length of each side of the square 'a'
The sum of length of all the sides (the perimeter) will be ,
a + a + a + a = 4a
Now let's equal this to the perimeter to find the length of each side 'a'

So the length of each side of the square is 2 cm
To find area of a square we multiply the length of its two sides
So,

is the area of the square,

The answer :
They can be customised depending on your use.
Answer:
The slope of this line is -1/2
Step-by-step explanation:
To find the slope of any equation, we need to use the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-13 - -15)/(11 - 17)
m = (-12 + 15)/(11 - 17)
m = 3/-6
m = -1/2
X=5/27 that should be the right answer
