sat og 第三套题第八套中的一道数学题
The pattern shown above is composed of rectangles.This pattern is used repeatedly to completely cover a rectangular region 12L units long and 10L units wide.How many rectangles of dimension L by W are needed?
答案是180,但我只算出来36
因为我怀疑我是不是理解错题目了

首先,楼主给的矩形的长为2L,宽为(5/3L),需要5个长为L宽为W的矩形拼成.
然后,我们要求一个长12L,宽6L的矩形,需要几个长为L宽为W的矩形拼成.
首先,我们可以知道,需要6*6个长为2L,宽为(5/3L)的矩形,即楼主所绘的图形.
然后,很容易的我们知道,需要6*6*5个长为L宽为W的矩形.即180个
楼主理解题目可能不准确.
rectangles of dimension L by W
指的是尺寸为L 和 W 的矩形,即长L 宽W 的矩形
题目问的是,长12L 宽10L 的矩形 需要 多少个长L 宽W 的矩形拼成
