Question

Which options represent a rearrangement of dots of the below figure?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (B)

The correct options are
A

B

18 can be factorised in the following ways:

$18=2\times 9$

$18=6\times 3$

$18=1\times 18$

The rectangles we choose must be such that the product of number of dots along the width and length must equal 18. Thus, the correct options are (a) and (b), whereas (c) represents a rectangle with $5\times 3=15$ dots and (d), a rectangle with $4\times 4=16$ dots are incorrect options.
