उत्तर

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
