To find the perimeter of a parallelogram, we need to add up the lengths of all four sides.
Given that two adjacent sides of the parallelogram are 5 cm and 7 cm long, we can use this information to determine the lengths of the remaining two sides.
The opposite sides of a parallelogram are equal in length, so both of the remaining sides will also be 5 cm and 7 cm long.
Therefore, the lengths of the four sides are:
- 5 cm
- 7 cm
- 5 cm
- 7 cm
We can now add up these lengths to find the perimeter:
Perimeter = 5 cm + 7 cm + 5 cm + 7 cm = 24 cm
Therefore, the correct answer is option A) 24 cm.

Perimeter of parallelogram is 2 (l+b)
=2 (5+7)
=2×12
=24cm
