Solution
\[\text{ We know that the opposite sides of a parallelogram are equal } . \]
\[\text{ Two sides are given, i . e . 4 cm and 3 cm } . \]
\[\text{ Therefore, the rest of the sies will also be 4 cm and 3 cm }. \]
\[ \therefore \text{ Perimeter = Sum of all the sides of a parallelogram }\]
\[ = 4 + 3 + 4 + 3\]
\[ = 14 \text{ cm }\]
