I) a) Transformtaion of reflection U at the centre of (5,9)
   b) Transformation of enlargement V at the centre J at the scale factor of 3

ii) Ai = ?
    Ao = 60 m^2
   
   Ao
   5 x 3 = 15 m^2
   60 / 15 m^2 = 4
  
   Ai
   10 x 6 = 60 m^2
    60 m^2 x 4 = 240 m^2
 
   Area shaded
   Ai - Ao = 240 m^2 - 60 m^2
               = 180 m^2
