1. Using a scale of 1:4000 draw an accurate map of the farm. 
2. Determine the actual area of the farm in hectares.
3. If the farm is on sale at sh.80,000 per hectare find how much the farm costs.

Answer 1

1. Using a scale of 1:4000 draw an accurate map of the farm. 
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
