Detailed Solution

The area of a parallelogram = 78089cm                       let the parallelogram be ABCD,
where АВ=CD = 26 см Assume the length of side A is b cm.
Area of parallelogram at    Base×height
 =. B×26
 Putting the value we get = 780 = 26×b
 On adjusting we get
 b= 780 /26
 =390/13
 realme
 b=390 /30
 =30  cm
