A rectangle is 12 feet long and 5 feet wide. If the length of the rectangle is increased by 25% and the width is decreased by 20%, what is the change in the area of the rectangle?
First let's find the area of the original rectangle: 12*5 = 60 Now for the new triangle: 1.25(12) * (1-0.2)(5) 15 * 4 = 60 There is no change in the rectangle.
