Question

Please help Find the area of the rectangle by multiplying its length and width.

Answer 1

the answer is D. man

Answer 2

Answer:

D.  $(21x2 - 17x + 2)\text{ square units }$

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,

$A=(7x-1)(3x-2)$

$=(7x-1)(3x)-(7x-1)(2)$  ( Distributive property )

$=21x^2-3x-14x+2$     ( Again by distributive property )

$=21x^2-17x+2$

Hence, Option D is correct.
