<img src="https://t1.daumcdn.net/cfile/cafe/142F600C496226D6AC" border="0" hspace="1" vspace="1" class="tx-daum-image" style="CLEAR: none; FLOAT: none" actualwidth="376" width="376" /> 이경우 아래 제발붙어랑님이 올려주신대로 푸는것도 훌륭하지만, 다른 손쉬운방법이있습니다. 삼각형의 넓이 = (삼각형의 각 변의 길이 )x(반지름)x1/2 라는 공식입니다. 공식대로 넣어보면, 삼각형의넓이 24 = 삼각형의 각 변의 길이 10+8+6 = 24 x 반지름 x 1/2 따라서 반지름은 2가 나오게됩니다. 다른경우에도 적용가능합니다.           <TABLE class="box_re_view conbox" cellSpacing=0 cellPadding=0 border=0> <TBODY id=COMMENT_STR> <TR vAlign=top> <TD style="PADDING-RIGHT: 0px" width=118> <IMG style="MARGIN: -2px 3px 0px 0px" alt=대표이모티콘 src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Ftjlab.co.kr%2F30%2FC601%2Fko%2FimgX%2Ftemplate%2Fico%2Fico_common_emoticon_01.gif" align=absMiddle>라이v</TD> <TD style="PADDING-LEFT: 0px">고1때인가 배우는 공식.. (2008-10-04 02:26:54)</TD></TR> <TR vAlign=top> <TD class=re_line colSpan=2></TD></TR> <TR vAlign=top> <TD style="PADDING-RIGHT: 0px" width=118> <IMG style="MARGIN: -2px 3px 0px 0px" alt=대표이모티콘 src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Ftjlab.co.kr%2F30%2FC601%2Fko%2FimgX%2Ftemplate%2Fico%2Fico_common_emoticon_01.gif" align=absMiddle>두션</TD> <TD style="PADDING-LEFT: 0px">키키킥 만세!!
