What measurements make a 20 m sq room?

Answer 1

A room that's 4.47 m on a side makes a 20 square m room

======================================

Answer #2:

You can't tell the measurements from knowing the area. There are an

infinite number of possibilities.

-- If the room is circular, then its diameter is about 5.046 meters. (rounded)

-- If the room is square, then each side is about 4.472 meters. (rounded)

-- If the room is a rectangle, then it could be

1 centimeter by 2 kilometers

1 meter by 20 meters

1.25 by 16

1.5 by 131/3

1.6 by 12.5

1.8 by 111/9

2 by 10

2.25 by 88/9

2.4 by 81/3

2.5 by 8

3 by 62/3

3.2 by 6.25

3.6 by 55/9

4 by 5

or any one of an infinite number of other pairs of dimensions. You can't tell.

In floor plans, most of the time the length and width are whole numbers or halves. Taking that into consideration, a 20m^2 room would have the following dimensions. 8m x 2.5m or 5m x 4m. I left out 10m x 1m because Ive never seen a room where the length was 10x the width or vice versa.
