  1.   The formula to calculate a length of rafter may be given as

Length of rafter = √ (rise)squared + (run)squared            

      (The whole of the RHS has been square rooted but cant type that symbol)

Transpose this equation and express in terms of the rise. Describe each stage so as to clearly identify what you have done.  Using this new equation calculate the rise if the length of the rafter is 7m and the run is 6. Write your answer to 3 s.f. 

 

 

If anyone has any ideas or could help it would be really appreciated. Thanks.
