Option 1: 52
Option 2: 56
Option 3: 68
Option 4: 72
Correct Answer: 52
Solution : Given: The lengths of the diagonals of a rhombus are 24 cm and 10 cm. So, the length of the sides = $\sqrt{(\frac{24}{2})^2+(\frac{10}{2})^2}$ = $\sqrt{12^2+5^2}$ = $\sqrt{169}$ = $13$ $\therefore$ The perimeter of the rhombus = (4 × 13) = 52 cm Hence, the correct
