### How many parallelograms are there in the given figure?

$210$
1. The number of row in the given figure $m = 4$
The number of column in the given figure $n = 6$
2. The total number of parallelograms in the figure \begin{align} &= \sum\limits_{m=1}^{ 4 } m \times \sum\limits_{n=1}^{ 6 } n \\ &= (1 + 2 + 3 + 4) \times (1 + 2 + 3 + 4 + 5 + 6) \\ &= 10 \times 21 \\ &= 210 \end{align}
