Question

Arrange 12 as a rectangle using dot pattern

Answer 1

Some numbers show as a square using dots.

The number 6 can be written in the form of rectangle.

Some numbers can be shown by two rectangles.

Let us take an example of 12

1) Firstly, we can arrange the dots either by 3 x 4. That means 3 rows and 4 columns.

2) Secondly, we can arrange the dots by 2 x 6. That means 2 rows and 6 column. Some numbers can also be arranged as triangles, such numbers are called triangular numbers.
