Answer 2

There are 144 squares in a chessboard-like grid containing 12 rows and 12 columns.

Step-by-step explanation:

Given:

The number of rows are given is 12

the number of columns are given is 12.

To be found:

The number of squares can be formed using the given rows and columns.

Solution:

Rows are horizontal lines.

Columns are vertical lines.

Let us assume number of rows (R) , columns (C) and squares (N)

The number of squares (N) are found by multiplying the row counts(R) and column counts(C).

Because the equal number of row and column lines creates the shape of a square.

Therefore, $N=R$  ×  $C$

$N=12$ × $12=144$

The number of Squares is 144.
