学习面积,是刘老师给我们布置的寒假作业。今天,我来告诉大家面积怎么算。先举一个例子:
The study area is the winter vacation homework assigned by Miss Liu. Today, I will tell you how to calculate the area. Here's an example:
这是一个鼠标垫,它的长约是24厘米,宽约是20厘米,请问它的面积是多少?
This is a mouse pad. Its length is about 24cm, and its width is about 20cm. What's its area?
很简单,拿它的宽和它的长相乘,就是它的面积。用数学公式表示为:24x20=480平方厘米
It's very simple. Multiply its width by its length, which is its area. Expressed by mathematical formula: 24x20 = 480 square centimeters
很简单吧?
It's easy, isn't it?
