Question

Figure ABCD represents a chess board room which is made up of 64 identical square of side 2 in each. Calculate the total area of the board.

• A. 256 sq. in
• B. 192 sq. in
• C. 384 sq. in
• D. 128 sq. in

Answer 1

The correct option is B 192 sq. in

Given:

Each side of a square = 2 in
$\text{Area of each square in the board =}sid{e}^2$
$=2\times 2$
$=4sq.in$

Total area of the chess board ABCD =
Number of squares x Area of each square

$=64\times 4$
$=256sq.in$
