Answer:
Length of one side = 44cm
The perimeter of the square = 176cm
Step-by-step explanation:
From the above square, we can see that two right triangles are formed by the diagonal and each two sides of the square.
So we can use Pythagorean Theorem to determine the length of one side of the square as shown below;
![\begin{gathered} 62^2=s^2+s^2 \\ 3844=2s^2 \\ s^2=(3844)/(2) \\ s=\sqrt[]{1922} \\ s=44\operatorname{cm}\text{ (to the nearest centimeter)} \end{gathered}]()
The perimeter of a square can be found using the below formula;
![P=4s]()
where s = length of each side of the square = 44cm
Let's substitute the value of s into the above formula and solve for P;
![P=4(44)=176\operatorname{cm}]()
