   The mermaid grew lilies, water lilies and lotuses for mermaids on a plantation that has the shape of a square with a side of 20 m. One-fourth of the plantation was planted with water lilies, one-fifth of the plantation with lilies. What area did the lotuses occupy?

   20 * 20 = 400m2
   400/4 * 1 = 100m2 water lilies
   400/5 * 1 = 80m2 lilies
   100 + 80 = 180m2 water lilies and lilies together
   400-180 = 220m2 lotuses
