उत्तर

Given one parallel side = 84 cm.

Let the other parallel side be ‘b’ cm.

Distance between a and b is h = 26 cm.

Area of the trapezium = 1586 sq.cm

`1/2 xx "h" xx ("a" + "b")` = 1586

`1/2 xx 26 xx (84 + "b")` = 1586

84 + b = `1586/13`

= 84 + b

= 122

b = 122 − 84

= 38 cm

∴ The other parallel side = 38 cm.
