Question

different rectangle/rectangles can be made by rearranging a set of $8$ square crackers.

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is B $2$

$2$ rectangles can be formed from a set of $8$ square crackers. This is because $8$ is a composite number and can be represented as a product of two natural numbers in the following ways:
$8=(1\times 8)\&8=(2\times 4)$

Hence $2$ rectangles can be formed.
