Question

Which of the following image does not represents the perfect rectangle of the number 12?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Factors of 12: 1, 2, 3, 4 , 6 , 12
$\therefore 1\times 12=12$

As there are 12 rectangles , it represent the perfect rectangle of dimensions of $12\times 1$

As there are 12 rectangles , it represent the perfect rectangle of dimensions of $3\times 4$

As there are 12 rectangles , it represent the perfect rectangle of dimensions of $6\times 2$

It does not represent perfect rectangle of 12 beacuse it does not have proper dimension .
$7\times 2$ = 14

$\therefore$ Option A is the correct answer
