Question 66125
The greenhouse floor has a diagonal equal to 28 feet. The sides are square. What is the length of one side?

We'll use the Pythagorean Theorem:

28^2=s^2+s^2
28^2=2s^2  take sqrt of both sides:

28=s(sqrt2)


s=28/sqrt2=19.799 feet

ck

(19.799)^2+(19.799)^2=28^2

392.005+392.005=784
784.010~~784
