The width of a rectangle is 3.4 units and the length is twice the width. The perimeter of this rectangle is how many units?
VLD [36.1K]
First, you must make sure that since the length is twice as big as the length.  That means that the length would be 6.8 because 3.4 x 3.4 = 6.8.  Then, since a rectangle has two long sides and two short sides, you add 6.8 + 6.8 + 3.4 + 3.4,  which equals 20.4(perimeter).
