1. In the U. S. the standard "Letter" size sheet of paper measures 82 x 11 inches. In all countries except the US and Canada, paper is sized using an International Standard (ISO) sizing system.
The dimensions of the standard printer paper, called ISO A4, in this system measures 210 x
297 mm.
a. Which paper has a larger perimeter?
b.
Which paper has a larger area?
c.
The dominance of the "Letter" format instead of ISO A4 as the common laser-printer
paper format in North America causes a lot of problems in daily international document
exchange between the U. S. and the rest of the world. A student in Ghana downloads an
electronic document in U. S. "Letter"-size with 1-inch margins on all sides. If the student
prints the document on ISO A4 paper, will the ISO A4 paper be wide enough and long
enough to contain the text of the U. S. "Letter”-size document? Remember to support
your argument with calculations.
