It depends on what its asking for and what dimension it is. If its 2D, the area is lengthXwidth, and perimeter you would add all the side lengths. If its 3D, volume is lengthXwidthXheigth.
38 1/4 as a decimal would be 38.25 because 1/4 is 0.25 add 38 to that would be 38.25
Expand the factored expression (multiply all the terms back together), and see if it matches up with the original expression.
D is the correct answer. To find this, take the total number, 25 and multiply it by 19% to get 21, which is the number of hard copies.
