Not a good question. What's the shape of the table? Square? Trapezoid? Triangle?

Shape of table depends on the way you think you can minimize the length.

Sonalika42, many of the questions you are posting are not representative of the official GRE. What is the source of this particular question?
In the future, when you post a question, be sure to note (anywhere in the post if need be) what the source is.

If you're preparing for the GRE, you would be well-served to use practice questions from reliable sources.

Hey

This is not a GRE question.

*****************************************************************************************************************************************************************

NOT RELATED TO GRE

Each member is 2.5 ft from every other member? No shape in 3 dimensions satisfies this condition. In three dimensions you can have maximum 4 points mutually equidistant.

3 on the ground on a equilateral triangle table and one hanging from the ceiling at 2.5 ft distance from other 3.

You dining table exists in 11 dimensional hyper-plane.
