• by joining the mid point of any qudrilateral we always get parallelogra.
  
  area of parallelogram = areaof quadrilateral / 2
  
  = 72/2
  = 36 sq cm

• if inner quadrilateral is rectangle or parall... outer quaddrilatral should we rectangle.
  
  then = a*b= 72.
  area of inner qudrilateral = a*b- 4*area of four tringle form when joining the mid point.
  so, a*b- 4*1/2*a/2*b/2 = 72- 4*72/8 = 36.
