A square bathroom window has diagonals of 42 inches. How many feet of trim will be needed for the frame? How many square feet of glass will be needed for the window pane?

The  side  of  the square  =  42/sqrt 2   inches

 

So.....the number of feet of trim  needed  =    4 * 42  / sqrt 2   ≈  118.8  inches = 118.8/12  =  9.9 ft

 

The sq ft  of   glass  needed =   4 * (1/2) 21^2  =  2 * 21^2   = 882 sq in   =  882/12^2  = 6.125 ft^2

 

Thanks  to EP  for spotting  my  earlier errror  !!!!!
