Answer:
D. [tex](21x2 - 17x + 2)\text{ square units }[/tex]
Step-by-step explanation:
Given,
The length of the rectangle = (7x-1) unit,
Its width = (3x-2) unit,
We know that,
The area of a rectangle = Length × Width
So, the area of the rectangle,
[tex]A=(7x-1)(3x-2)[/tex]
[tex]=(7x-1)(3x)-(7x-1)(2)[/tex] ( Distributive property )
[tex]=21x^2-3x-14x+2[/tex] ( Again by distributive property )
[tex]=21x^2-17x+2[/tex]
Hence, Option D is correct.
