Solution
Given:
Lengths of the parallel sides are 16 dm and 22 dm.
And, height between the parallel sides is 12 dm.
Area of trapezium \[\frac{1}{2}\times(\text{ Sum of the parallel sides })\times(\text{ Height })\]
\[ = \frac{1}{2} \times (16 + 22) \times (12)\]
\[ {=228 dm}^2 \]
\[ = 228 \times dm\times dm\]
\[=228\times\frac{1}{10}m\times\frac{1}{10}m\]
\[ = 2 . 28 m^2\]
