In a rhombus ABCD, AO=6 cm and BO=8 cm. How much is the perimeter of this rhombus?
(A) 28 cm (B) 35 cm
(C) 40 cm (D) 48 cm
(E) None of the above
In a rhombus diagonals bisect each other at . Therefore, .
In , we have
Sides of rhombus are equal. Therefore, perimeter = 4 side cm
Hence, the answer is (C).
