Answer:

Aqua: 26.8cm

Purple: 36cm

Explanation:

  1. (13.4*4)/2 = 26.8 = aqua
  2. 2((9*4)/2) = 36 = purple
  3. 36 + 26.8 = 62.8 = total area

Area of aqua: A = bh/2 = (13.4cm) (4cm)/2 = 26.8cm2

Total area trapezoid: A = (a+b/2)h = ((13.4cm + 18cm)/2) 4cm = 62.8cm2

Area of purple = Total area - area of
aqua = (62.8cm2) - (26.8cm2) = 36cm2
