Question 1049062
the dimensions of a rectangle are {{{2x+1}}} and {{{x-1}}}

{{{(2x+1)(x-1)}}}

{{{2x^2-2x+x-1}}}

{{{2x^2-x-1}}}->the area before dimensions are increased


 if each dimensions are increased by {{{2}}} units, we have

{{{2x+1+2}}} and {{{x-1+2}}}

{{{2x+3}}} and {{{x+1}}}

the area is:

{{{(2x+3)(x+1)}}} 

{{{2x^2+2x+3x+3}}} 

{{{2x^2+5x+3}}} ->expression that represents increase in area
