Solution
Lengths of the parallel sides are 1.2 m and 1 m and the perpendicular distance between them is 0.8 m.
∴ Area of the trapezium shaped surface \[=\frac{1}{2}\times(\text{ Sum of the parallel sides })\times(\text{ Perpendicular distance })\]
\[ = \frac{1}{2} \times (1 . 2 + 1) \times (0 . 8)\]
\[=\frac{1}{2}\times2.2\times0.8\]
\[ {=0.88 m}^2\]
