haha, I actually read your blog everynight. no wonder you don't have time for gathering, even updating blog is so hard to you. saw the question, the scanned image is too blur, can't tell which part of it is "shaded". But sounds easy anyway wor?! so far if the shaded areas are in the 'triangle(s)', as all triangles are with a right angle ma... using Butt's (?) theory to calculate ma... anyway, when u free guys, too eager to see, not you (hehe, just lunched with you) but scanner and others. |
