# Arectangle has a height of x+9x+9x, plus, 9 and a width of x^2+2xx 2 +2xx, squared, plus, 2, x.

Step-by-step explanation:

7x^2 + 4x

Step-by-step explanation:

length is 7 times the width

Step-by-step explanation:

area=x^2+3x+2 * x+4

=x^3+3x^2+2x+4x^2+12x+8

=x^3+7x^2+14x+8

area of rectangle=(x+4)(x^2+3x+2)

Step-by-step explanation:

area of rectangle=

area of rectangle=

where, length=height=(x+4)

width=(x^2+3x+2)

area of rectangle=(x+4)(x^2+3x+4)

Step-by-step explanation:

the area of a rectangle is:

in this case we know the following:

height:

width:

so to get the area we must muliply these two expressions:

and making the operations we get:

the expression is the area of the entire rectangle

4x+7

Step-by-step explanation:

(7x² - 4x) unit²

Step-by-step explanation:

Area of rectangle = width × height

Width = 7x - 4

Height = x

Area = x ( 7x - 4)

Area = (7x² - 4x) unit²

(7x² - 4x) unit²

Step-by-step explanation:

Area of rectangle = width × height

Width = 7x - 4

Height = x

Area = x ( 7x - 4)

Area = (7x² - 4x) unit²

Area = A =

Step-by-step explanation:

Given Data:

Height of rectangle = x

Width of rectangle = 7x – 4

To find out:

Area = A =  ?

Formula:

Area = A = l×h

Solution:

Area = A = l×h

Area = A = x × (7x – 4)

Area = A =
