Why is the area of a rectangle calculated by multiplying length by width?

Answer 1

Well, isn't that a happy little question! When you multiply the length of a rectangle by its width, you're essentially finding out how many little squares can fit inside it. Each little square represents a unit of area, so by counting up all those squares, you get the total area of the rectangle. It's like a beautiful math garden where every calculation adds a touch of joy and understanding.

Answer 2

If someone fills the inside of the rectangle by drawing hundreds of rows of tiny squares,

the way you find out how many squares there are is: you count the number of rows,

then you count the number of columns, then you multiply the two numbers.

That's exactly what you're doing when you measure the width, measure the length,

and multiply.
