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

(7x-1) width (3x-2) length

a.

(21x2 + 11x + 2) square units

b.

(21x2 − 11x + 2) square units

c.

(21x2 + 2) square units

d.

(21x2 − 17x + 2) square units

D.  

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,

 ( Distributive property )

    ( Again by distributive property )

Hence, Option D is correct.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
