在正方形里面画出四个小三角形（如图）,三角形①与②的面积比是2:1；三角形③与④的面积相等,三角形①
+②+③的面积之和是1/4平方米；三角形②+③+④的面积之和是1/6平方米,那么四个小三角形的面积总和是多少平方米?（急救,现求）
我比较不懂意思，请详解
在正方形里面画出四个小三角形（如图）,三角形①与②的面积比是2:1；三角形③与④的面积相等,三角形①+②+③的面积之和是1/4平方米；三角形②+③+④的面积之和是1/6平方米,那么四个小三
设三角形2的面积为X 三角形3的面积为y
2x+x+y=1/4
x+y+y=1/6
x=1/15 y=1/20
2x+x+y+y=3/10
设三角形1，2，3，4的面积分别为a,b,c,d.总面积为x 依据题目得 a=这四个小三角形的面积总和是3/10平方米 没图啊 设三角形II、
朋友，你的题是否出错了，也看不到图。根据已知计算后，相互矛盾。
