Answer:
Taking a square area, a 36 perimeter will represent a 9 as the x value.
Step-by-step explanation:
We have the perimeter of a geometric figure.
Let's suppose we have a square shape and let x be the value of the side of the square.
The area of the square will be the square of the side A = x*x.
The perimeter of the square will be the sum of 4 sides. As it is a square, all sides have the same value. P = x +x +x +x = 4*x
We have a perimeter of 36. We can find x isolating from:
36 = 4*x
x = 36/4
x =9.
Finally, x has to be 9 as the side of a square for the 36 perimeter.
