A football field is 100 yards long and 50 yards wide. How do you find the length of a diagonal of the football field?
A football field is a rectangle, so a diagonal line creates 2 right triangles. The formula for the length of the sides of a right triangle is
The length of the diagonal is
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
