Question 896893: Topic-Problem-solving with Perimeter, Area, and Volume
In the U.S. the standard “Letter” size sheet of paper measures 8˝ x 11 inches. Elsewhere in the world, 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.If you wanted to print a document formatted to the size of ISO A4 paper onto U.S.“Letter”-size paper, do you think the margins would look bigger or smaller?Why

1 inch = 2.54 centimeter

US Letter Sized, 8.5*2.54 by 11*2.54 centimeter by centimeter

US Letter Sized,
Perimeter=2%2A2.54%2A%288.5%2B11%29=99.06%2Acm
Area=8.5%2A11%2A2.54%5E2=603.22%2Acm%5E2

ISO A4,
21 by 29.7 cm by cm
Perimeter=2%2821%2B29.7%29=101.4%2Acm
Area=21%2A29.7=623.7%2Acm%5E2

Answer a and b from the computations done above.
(c), the margins would be larger. More area for taking the printed document contents a small bit of it going unused compared to US Letter size.
