The diagonals if a rectangle are equal 1 always 2 sometimes 3 never

Remember that a rectangle has four equal angles, that the side lengths are equal and that the end lengths are equal. Under these circumstances the diagonals are of equal length.

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
