A) 80 cm
B) 72 cm
C) 68 cm
D) 64 cm
Correct Answer: A
Solution :
We know that, rhombus is parallelogram whose all four sides are equal and its diagonals bisects each other at \[90{}^\circ .\] \[\therefore \] \[AB=\sqrt{{{(16)}^{2}}+{{(12)}^{2}}}\] \[=\sqrt{256+144}=\sqrt{400}\] = 20 cm = side of the rhombus \[\therefore \]Perimeter of the rhombus \[=20\times 4=80\,\text{cm}\]You need to login to perform this action.
