<PRE><B>Question 133398</B>
the diagonals of a rhombus are perpendicular; and, like all parallelograms, they bisect each other


this means that the side of the rhombus is the hypotenuse of a right triangle formed by half of each diagonal and the side


by Pythagoras __ s^2=(14/2)^2+(12/2)^2 __ s^2=7^2+6^2 __ s^2=49+36


C is looking pretty good</PRE>
