  1. Using a scale of 1:4000 draw an accurate map of the farm. Mathf4et121p1a21
  2. Determine the actual area of the farm in hectares. 
    Area A = ½ x 60 x 60 = 1800
    B = ½ (60 + 100) x 200 = 2600
    C = ½ (100 + 120) x 60 = 6600
    D = ½ x 80 x 120 = 4800
    E = ½ x 160 x 200 = 16000
    F = 20 x 160 = 3200
    G = ½ (120 + 160x 60 = 8400
    H = ½ x 100 x 120 = 6000
                                 =72800
    72800 = 7.28 ha
         1000
  3. If the farm is on sale at sh.80,000 per hectare find how much the farm costs.
           7.28 x 80,000 = sh.582400
