This value is very different from the other values
162 m^2
you can make a triangle in the corner with legs length s/2 and the angles are 45 degrees. in a 45 45 90 triangle, the legs are h/sqrt(2) where h is the hypotenuse. this means that s/2=9/2 sqrt(2), s=9 sqrt(2)
and s^2=162
Step-by-step explanation:
you first need to know what is mean .mean is when you add all the numbers up then divide them by 2
