प्रश्न

Find the missing values.

Height 'h' Parallel side 'a` Parallel side 'b` Area
  13 cm 28 cm 492 sq.cm
योग

उत्तर

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
