Since when you draw the diagonal, the rectangle becomes 2 right triangles.
The hypotenuse is now the diagonal
the legs are both 10 and 6
To find the hypotenuse of a triangle, you can use the Pythagorean theorem
(a^2+b^2=c^2) a and b are the legs c is the hypotenuse.
let a=6
let b=10
plug into Pythagorean theorem
6^2+10^2=c^
36+100=c^2
136=c^2
c= sqrt(136) = 11.6619038
Answer: sqrt136 or 11.6619038
