Solution
Given the parallel sides a = 13 cm, 6 = 28 cm
Area of the trapezium = 492 sq.cm
`1/2` h(a + b) = 492
`1/2` × h × (13 + 28) = 492
h × 41 = 492 × 2
h = `(492 xx 2)/41`
h = 24 cm
Tabulating the results we get
| Height 'h' | Parallel side 'a` | Parallel side 'b` | Area |
| 24 cm | 13 cm | 28 cm | 492 sq.cm |
