Have a look at these five rectangles:
Length . . . Width
1 . . . . . . . . 3,000
10 . . . . . . . 300
15 . . . . . . . 200
30 . . . . . . . 100
50 . . . . . . . 60
All five of them have the same area ... 3,000 ... but their perimeters are
6002, 620, 430, 260, and 220.
Knowing the area doesn't tell the perimeter. For any area you name, there are
an infinite number of differemnt rectangles, with different dimensions, that all
have that same area.
