The sides of a rectangle were reduced by 60% of their original dimensions. The area of the new rectangle represents what percent of the area of the original rectangle?
L * W = 1.6L * xW Divide both sides by LW 1 = 1.6 * x divide both sides by 1.6 = x x = .625, new width = .625*old width, therefore 1 - .625 = .375 * 100 = 37.5 decrease in the width to have the same area
