Re: QOTD #10 The length of each side of rectangle R is integer [#permalink]

Why the length can't more than 7? Say, if length=7, breadth will be 36/7 and so on ? The information is only about length being an integer, it hasn't said anything about breadth, I mean it doesnot say if breadth is an integer as well.

Your argument makes sense. This is the official ETS explanation. It is very unusual that ETS makes mistakes such as this one.

Hi,

One of the options that they give is a 6X6 rectangle...but a rectangle doesn't have four equal sides. It would be a square, right? I know that option B would still be the right answer regardless but if 6x6 is considered a square wouldn't it be four values for the perimeter rather than 5? Hope this makes sense.

A square is still a rectangle. A special type but a rectangle.

We can add to this....

A parallelogram is a special kind of quadrilateral
A rectangle is a special kind of parallelogram
A square is a special kind of rectangle


We can also write:
A parallelogram is a special kind of quadrilateral
A rhombus is a special kind of parallelogram
A square is a special kind of rhombus
