What are the dimension of 45 square feet?

Answer 1

You can't tell the dimensions from knowing only the area. There are an infinite number

of different shapes, all with different dimensions, that all have the same area.

Even if you restrict it to only rectangles, there are still an infinite number of rectangles

with different dimensions that all have the same area.

Here are a few examples:

1 x 45

2 x 22.5

3 x 15

3.75 x 12

4 x 11.25

5 x 9

5.625 x 8

6 x 7.5

10 x 4.5

All of these rectangles have the same area . . . it's 45.
