a) A standard sheet of paper measures 8 1/2 by 10 inches.
The area of one such sheet of paper is 0.0549m^2
A second sheet of paper is three-quarters as long and three-quarters as wide as the one described in part (a). By what factor is its area less than the area found in part(a)?
I understand that all you have to do is (.75)(.75) to get the percentage but by what FACTOR would this be off by?
Thanks so much for your help! God Bless!! :)

You just answered your own question:
The original paper was (1)(1) = 1
The new paper is (.75(.75) = .5625 = 56.25% of the original area of the original paper
So, multiply .0549m^2 by .5625 to get your answer

It should be totally accurate. By the way, the stanard sheet of paper in the USA is 8 1/2 by 11 inches.
