The lengths of the diagonals of a rhombus are 16 cm and 30 cm, respectively. What is the perimeter of the rhombus?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 68
(The side of the rhombus)2 = (16/2)2 + (30/2)2
⇒ side2 = 82 + 152
⇒ side2 = 64 + 225 = 289
Thus, the side = 17 cm
The perimeter of the rhombus = 4 × 17 = 68 cm
