For this challenge, why does it help to think about the cross-section and not at all about how long the gutter might be?<br /><br />Hope the above helps!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1913386204966570981-6652603326052052534?l=temasek-maths-geometry.blogspot.com' alt='' /></div>Mr Tohhttp://www.blogger.com/profile/04734043704751425014noreply@blogger.com0tag:blogger.com,1999:blog-1913386204966570981.post-30153029953385597052007-07-19T21:16:00.000+08:002007-07-19T21:29:01.951+08:00<div>Well students, here's your first problem. </div><br /><div>Please think through the problem and enter your answer via the comments section (Just click on the <em>comments</em> button below). </div><br /><div>There is no limit as to the number of times that you can answer each problem, but please take note of the following rules for comments:</div><br /><div>1) Watch what you type into comments (No unrelated comments and No vulgarities), </div><br /><div>2) Do leave your name & class for each of your comments (i.e. <em>name_sec3X). </em>This is to enable me to take note of who's who in the math blog. </div><br /><div></div><br /><div>This weeks' problem is related to finding area and perimeter...if you are ready, here's the problem: </div><br /><div>A plastic gutter is designed to catch water at the edge of a roof. <img id="BLOGGER_PHOTO_ID_5088898883951857778" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://bp0.blogger.com/_Grq0zxDiQ1Y/Rp9mkqPVEHI/AAAAAAAAAAU/wfwRJwDo_5k/s320/Gutter.jpg" border="0" /></div><div>Manufacturers need to minimise the amount of material used to make their product.
