  2.
  a)
  a = 8 cm
  h = 2 cm
  
  P = \frac{1}{2} * a * h
  
  P = \frac{1}{2} * 8 * 2 = 8 cm^{2}
  
  b)
  a = 8 cm
  h = 4 cm
  
  P = \frac{1}{2} * 8 * 4 = 16 cm^{2}
  
  c)
  a = 8 cm
  h = 8 cm
  
  P = \frac{1}{2} * 8 * 8 = 32 cm^{2}
  
  d)
  a = 8 cm
  h = 16 cm
  
  P = \frac{1}{2} * 8 * 16 = 64 cm^{2}
  
  e)
  a = 8 cm
  h = 32 cm
  
  P = \frac{1}{2} * 8 * 32 = 128 cm^{2}
  
  3.
  a)
  a = 2 cm
  h = 6 cm
  
  P = \frac{1}{2} * 2 * 6 = 6 cm^{2}
  
  b)
  a = 4 cm
  h = 6 cm
  
  P = \frac{1}{2} * 4 * 6 = 12 cm^{2}
  
  c)
  a = 8 cm
  h = 6 cm
  
  P = \frac{1}{2} * 8 * 6 = 24 cm^{2}
  
  d)
  a = 16 cm
  h = 6 cm
  
  P = \frac{1}{2} * 16 * 6 = 48 cm^{2}
  
  e)
  a = 32 cm
  h = 6 cm
  
  P = \frac{1}{2} * 32 * 6 = 96 cm^{2}
  
  4.
  a)
  a = 5 cm
  h = 14 cm
  
  P = \frac{1}{2} * 5 * 14 = 35 cm^{2}
  
  b)
  a = 21 cm
  h = 8 cm
  
  P = \frac{1}{2} * 21 * 8 = 84 cm^{2}
  
  c)
  a = 4,6 cm
  h = 4 cm
  
  P = \frac{1}{2} * 4,6 * 4 = 9,2 cm^{2}
  
  d)
  a = 8 cm
  h = 2 \frac{1}{2} cm
  
  P = \frac{1}{2} * 8 * 2 \frac{1}{2} = 10 cm^{2}
  
  5.
  a)
  a = 6 cm
  b = h = 8 cm
  
  P = \frac{1}{2} * 6 * 8 = 24 cm^{2}
  
  b)
  a = 6 cm
  b = h = 12 cm
  
  P = \frac{1}{2} * 6 * 12 = 36 cm^{2}
  
  c)
  a = 8 cm
  b = h = 4,5 cm
  
  P = \frac{1}{2} * 8 * 4,5 = 18 cm^{2}
