You can put this solution on YOUR website! Hint: If the side length of the square is x, then where d is the diagonal. So because the diagonal is 18 m, we know that d = 18 and
Once you have the side length, you can plug it into the formulas
You can put this solution on YOUR website! The diagonal length is the hypotenuse to a right triangle where the sides have equal length
From the Pythagorean theorem we know that
Since the sides a and b are the same we can rewrite it as
combine like terms
divide both sides by 2
Since is my area formula for a square, 162 is my area.
The perimeter will be 4*s
take the square root of both sides
s=12.73m
4s=50.91
