Answer:
3x - 1
Explanation:
Area of the Rectangle:
18x^2 - 6x
6x (3x - 1)
Width = 6x
Length =?
Area of Rectangle = Length * Width
Length = Area/breadth
6x (3x -1) / 6x cross out 6x
Thus, Length of Rectangle = 3x - 1
length = 3x - 1
Area of a rectangle = length x width
or using l = length, w = width and A = area
A = l x w
or
l = A/w
GivenA = 18x² - 6xw = 6x
l = 18x²- 6x/6x
= 18x²/6x - 6x/6x
= 3x - 1
