Are there other possibilities? What if the value of area given is very huge or in decimal? Would this method still work effectively and efficiently? (You would have to consider using algebra then). <br /><br />The conversion is clearly explained. On what basis did you multiply by "100"? <br /><br />"cm^2" should be read as "square centimetre".LOH Kwai Yinhttp://www.blogger.com/profile/06503397685892227762noreply@blogger.com
