Answer:
The area of rectangle is (8x² - 4x) units² .
Step-by-step explanation:
Given that the area of rectangle formula is A = length×breadth. Then substitute the following expressions into the formula :
[tex]area = length \times breadth[/tex]
Let length = width = 2x² - x,
Let breadth = height = 4,
[tex]area = (2{x}^{2} - x) \times (4)[/tex]
[tex]area = 4(2 {x}^{2} ) - 4(x)[/tex]
[tex]area =( 8 {x}^{2} - 4x) \: \: {units}^{2} [/tex]
