Mathematics

Step-by-step explanation:

Diagonals of a rhombus are perpendicular bisector.

Hence, triangle ABE so formed would be a right triangle right angled at E.

Therefore, by Pythagoras theorem:

$AB = \sqrt{AE^2 + BE^2 } \\ \\ \therefore \: AB = \sqrt{5^2 + 12^2 } \\ \\ = \sqrt{25 + 144} \\ \\ = \sqrt{169} \\ \huge \red { \boxed{ \therefore \: AB= 13}}$
