(x + 1/x)^2 = x^2 + 1/x^2 + 2(x)(1/ x) = 62 + 2 = 64 x + 1/x = sqrt 64 = 8 or -8. Since x is postive, 8 is the answer

The area of one rectangular strip of paper is 10x2=20cm^2. The piece of cardboard has an area of 20x12=240cm^2(deducing from the three rectangular strips pasted on it). Thus the area of the cardboard that is not covered is 240-3x20=180cm^2.
