Question

Which one of the following numbers can be represented by 3 different rectangles?

• A. 30
• B. 13
• C. 10
• D. 5

Answer 1

The correct option is A 30

For option ‘a’: 30 can be written as $10\times 3$, $15\times 2$, $6\times 5$

So it can be represented by 3 different rectangles.

For option ‘b’: 13 can be written as $1\times 13$. So it can be represented by just a line.

For option ‘c’: 10 can be written as only $5\times 2$. So it cannot be represented by 3 different rectangles.


For option ‘d’: 5 can be written as $1\times 5$. So it can be represented by just a line.

So, option 'a' is the correct option.
