   Print "Enter the length and width of the house in metres -- "
   Get houseLength houseWidth

Comment : calculate the area of the lawn
   lawnArea = yardLength*yardWidth - houseLength*houseWidth
   
Comment : calculate the cost to mow the lawn
   cost = lawnArea * squareMetreCost

Comment : calculate the cost to mow the lawn on the weekend
   weekendCost = cost + (1/3)*cost

Comment : display the results
