Answer:
See below, please
Explanation:
This square
Hence,
Because x is positive, So,
Then we know
The length of one of the sides
The area of the square
The perimeter of the square
Value of X: X=2
Length of One Side: 31
Area: 961u^2
Perimeter: perimeter = 124
Set the sides equal to each other, simplify and then use quadratic equation. One result is positive and the other is negative, shape's sides have to be positive so use the positive value for X.
