Area of floor of cone = \pi  r^{2} where r = radius of cone
  \pi r^{2} = 616 sq ft 
 So,  r^{2} = 616 x 7/22 = 196 sq ft
  =>  r^{2} = 196    => r = 14 ft
  We know that  l =  \sqrt{r ^{2}+ h ^{2}  } where l = slant height ,   r   = radius of cone and h = height of cone.
  l = \sqrt{14 ^{2} +( 2 \sqrt{5}) ^{2}  }
  l = 6 \sqrt{6} ft
