①将一个正方形划分成为五个相同的长方形,每个长方形（题目打错了）的周长为30厘米,你可以不用设X就求出这个广场周长吗?
30/5*（5-1）*4=96（cm）square应翻译成正方形
②一个小正方形的边长为4厘米,如果我们使之成为一个大正方形需要9个这样的小正方形,这个大正方形的周长是多少?
9=3*3 4*3*4=48（cm） side length意思是边长
③我们用一些小长方形拼成一个大长方形,大长方形的面积是270平方厘米,你能算出大长方形的周长吗?
题目缺少条件,做不出来.
④三个边长15厘米的正方形拼成一个长方形,这个长方形的周长是多少?
15*（3+1）*2=120（cm）

1. 50cm
2. 48cm
3. I can't work out the answer.
4. 120cm

做个标记学习下

翻译得不太准确。但还是能看懂的。
1 .广场是分成5个长方形组成,每个reactangle的周长是30厘米,如果你不设定x,你能算出的周长这个广场吗?
' s侧具有浓厚小广场长度是4厘米,如果我们做出这样9成了一个大广场,广场的周长是多少这个大广场吗?
大立方体,3.we困惑,一些很小的长方形的面积大的长方形270cm²,你能算出的周长大长方形吗?
4.t...
