The greenhouse floor has a diagonal equal to 28 feet. the sides are sguare. what is the length of one side?
Since it is a square floor the sides are equal.
Let each side be x
The diagonal and the two sides form a right triangle. The diagonal beomes the hyotenuse.
Using the Pythagorus theorem : (side)^2 +(side)^2 = Hypotenuse ^2
x^2+x^2 = 28^2
2x^2=784
x^2= 784/2
x^2= 392
x= sqrt 392
x=19.79
