Question

What is the length of the diagonal of a square with the side of 5 feet?

Answer 1

Remember our friend Pythagoreas and his famous Phythagorean Theorem? Let's call on him for help. If you have a right triangle (that is, a triangle that has one 90 degree angle), and if a and b are the lengths of the shorter two sides, and if c is the longest side (better known as the "hypotenuse," then \[a^2+b^2=c^2\]

Answer 2

if a = b = 5 ft, calculate c^2. Then calculate c.
