  1. Part (i): To derive the equation, should elaborate, on what basis you know that the 2 expressions are equal. The explanation to solve the equation is clear (the balancing).

    Part (ii): You could have add on 'facts' like area of rectangle is length x breadth, that would explain why you say area of rectangle is 23 times 10. The unit "cm^2" should be read as "square centimetre".

    Part (iii): The conversion steps are very clearly written and explained. Well done :)
