1. Answer:

   84

   Step-by-step explanation:

   Given:

   Area of the trapezium =1586 cm

   2

   Distance between the parallel sides =26 cm

   And, length of one parallel side =38 cm

   Let us suppose the length of the other side to be x cm.

   Now, area of the trapezium =

   1/2× (Sum of the parallel sides)× (Distance between the parallel sides)

   ⇒1586= 1/2 ×(38+x)×(26)

   ⇒1586= 26/2 ×(38+x)

   ⇒13×(38+x)=1586

   ⇒38+x= 1586/13

   ​⇒38+x=122

   ⇒x=122−38=84 cm

   Hence, the length of the other parallel side is 84 cm.
