An artist drew a rectangle. the artist then modified the rectangle so thatthe length ofthe rectawngle increased by 30 percent and the width of the rectangle decreased by 40 percent. after the modification, what was the percent decrease in the area of the rectangle?
the dimensions of the original rectangle length - L width - W area = L*W = LW after the modification, new dimensions are length increased by 30 % Length = L * 1.3 = 1.3L Width = W * 0.6 = 0.6W new area = 1.3L * 0.6W = 0.78LW the percent decrease in area decrease % = (difference in area)/original area * 100 = (LW - 0.78LW)/LW * 100 = 0.22LW/LW * 100 = 22% percent decrease is 22%
