Question

different rectangle/rectangles can be made using a set of $5$ square crackers.

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is A $1$

Only $1$ rectangle can be formed from a set of $5$ square crackers. This is because $5$ is a prime number and cannot be represented as a product of any two numbers other than $1$ and itself.

Hence only one ($1\times 5$) or ($5\times 1$) rectangle can be formed.
