You have explained clearly how the equa...Part (i): <br />You have explained clearly how the equation is formed. <br />However, instead of describing it as 'shifting', you should add on to describe how you 'shift' and why - to add "-3" to both sides of the equation so that the equation remains balanced yet you are able to 'remove' the numerical value on the LHS of the equation.<br /><br />Part (ii): You have given the correct formula and also mentioned about substituting the x value into the equation to find the numerical values of length and breadth. <br />However, while the screen shows cm^2, you were reading it as cm^3. So, what's exactly the unit?<br />The unit should be read as "square cm" or "cubic cm".<br /><br />Part (iii): You have explained that due to the conversion 1 m = 100, that's why divide it by "100x100". Good.<br />However, note that the numerical answer in the clip is incorrect. It should be 0.023m^2LOH Kwai Yinhttp://www.blogger.com/profile/06503397685892227762noreply@blogger.com
