Express the area of the entire rectangle.

Cloud [144]

Answer:

$\huge\boxed{A=x^2+12x+35}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=lw$

<em>l</em><em> - length</em>

<em>w</em><em> - width</em>

We have

$l=x+7\\\\w=x+5$

Substitute:

$A=(x+7)(x+5)$

Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>

<em></em> $A=(x)(x)+(x)(5)+(7)(x)+(7)(5)\\\\A=x^2+5x+7x+35$ <em></em>

combine like terms

$A=x^2+(5x+7x)+35\\\\A=x^2+12x+35$
