Question 77906
1)

The area is simply the base multiplied by the height:

{{{(2x+1)(2x+1)=2x*2x+2x+2x+1=4x^2+4x+1}}} foil the terms

So the area is {{{4x^2+4x+1}}}



2)Again to find the area, we just multiply the base and the height:

{{{(3x+2)(3x-2)=3x*3x+6x-6x-4=9x^2-4}}} foil the terms

So the area is {{{9x^2-4}}}
