Question from ranjan, a student:

if we make a rectangle with a 100cm of wire, then its area will be?

Hi Ranjan,

There are many different rectangles you can make from 100 cm of wire. it could be 30 cm by 20 cm, 40 cm by 10 cm, 49 cm by 1 cm, or many other dimensions. It could even be 30.3 cm by 19.7 cm, there is no reason the dimensions have to be integers. Each of these rectangles have a different area, you should calculate them. The length of the wire alone is not enough information to determine the area.
