Piece of wood width 1 sits over a square tile through opposite corners (see pic) What proportion of the area of the tile is covered by the wood?

Bad drawing, u probably should do your own.....:-)
If u can see it opposite edges of the wood are aligned with corners of tile.

@JamesWolf U should be practicing your Python!:-)
That pic is not correct, the edges are aligned with the corners, not in the middle...
so a is the angle between the middle of the wood and the side of the square which is 90/2 = 45. the bottom of that triangle has length 1/2. we need to find b. then you can do "length of square" - b = side of triangle|dw:1350379684247:dw|
righttt sorry
opposite corners, yes i should be doing python! stupid python
:-)
i think |dw:1350379781386:dw| is the same as |dw:1350379796776:dw|
