A poster is to have an area of 180cm^2 with 1-cm margins at the bot and sides and 2-cm margin at the top.
What dimensions will give the largest printed area?
到底是要求什么啊,尺寸不是已经在题目里说了嘛?The largest printed area是什么呀..

一张海报面积为180,上边距为2,左右边距和下边距为1,求印刷面积最大时的海报的尺寸(长、宽).

只是给面积 180平方厘米,下边框,左右边框 1厘米,上边框为 2厘米,要你求出这个长方形的长、宽是多少时,可画的面积最大啊
设长为x, 宽为y,, xy =180
求可画的面积 = (y-1-2)(x-1*2) 的最大值

给出的尺寸是整个海报的大小,问的是去除边框后中间可打印区域的大小。

求除了边际以外的可以打印的面积
总面积180平方厘米,两边和下面边际1厘米,上面边际两厘米。求中间面积。
设长为x,宽为y,(x-3)*1+3y=? x*y=180
