Solution
Given: height ‘h’ = 19 m
Parallel sides b = 16 m
Area of the trapezium = 323 sq.m
`1/2` h(a + b) = 323
`1/2` × h × (a + 16) = 323
a + 16 = `(323 xx 2)/19` = 34
a = 34 – 16 = 18 m
a = 18 m
Tabulating the results we get
| Height 'h' | Parallel side 'a` | Parallel side 'b` | Area |
| 19 m | 18 m | 16 m | 323 sq.m |
