Two square fields jointly contain 123 hectares and the side of one is four-fifth as long as that of the other.How many hectares does each contain?

• 75, 48 hectares
  
  If One square field has side=x hectares, then another will have 4x/5 hectares
  Given, Area of both is 123 hectares, so x^2+ (4x/5)^2=123, x^2=75
  So one field contains x^2=75 hectares and another (4x/5)^2=16x^2/25=48 hectares
