[12 April 2016] Challenging Question 1 - Linear Equations

17 submissions were received this morning and almost all of you managed to get the answers correct. However, many of you did not express the information clearly in algebra (which is expected). In addition, many of you included the unit (cm) in the equation. This caused confusion (whether the letter represents a variable or unit).


  • Express the information in an equation
  • Write a word/ statement to describe what you are finding (e.g. Perimeter, Area) to add meaning to the string of numbers
  • Check to write the correct unit at the end of the presentation
