Problem Statement

The length of rectangle R is 10 10 percent more than the side of square S. The width of the rectangle is 10 10 percent less than the side of the square. The ratio of the areas, R:S, is: <spanclass=latexbold>(A)</span> 99:100<spanclass=latexbold>(B)</span> 101:100<spanclass=latexbold>(C)</span> 1:1<spanclass=latexbold>(D)</span> 199:200<spanclass=latexbold>(E)</span> 201:200 <span class='latex-bold'>(A)</span>\ 99: 100 \qquad <span class='latex-bold'>(B)</span>\ 101: 100 \qquad <span class='latex-bold'>(C)</span>\ 1: 1 \qquad <span class='latex-bold'>(D)</span>\ 199: 200 \qquad <span class='latex-bold'>(E)</span>\ 201: 200
