+120 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?
+128475 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 !!!!!
