The given pair of angles are vertical opposite angle pair so, they are equal. i.e
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.
12 is 20% of 60 because 12/60 = 0.2.
Answer: The distance between W and X
