Algebra.Com's Answer #129268 by solver91311(24713)![]() ![]() You can put this solution on YOUR website! I can't tell from your description how the pins are arranged on your Geoboard. Visit http://www.cut-the-knot.org/Curriculum/Geometry/Geoboard.shtml and you can set the pins yourself and the applet will calculate the area for you. \n" ); document.write( " |
