Question 309894
To find the trinomial, simply FOIL {{{(3x + 2)(2x + 3)}}} to get


{{{A(x)=(3x + 2)(2x + 3)=6x^2+9x+4x+6=6x^2+13x+6}}} which means that the trinomial is {{{A(x)=6x^2+13x+6}}}



Now plug in x=3 and evaluate: 



{{{A(x)=6x^2+13x+6}}}



{{{A(3)=6(3)^2+13(3)+6}}}



{{{A(3)=6(9)+13(3)+6}}}



{{{A(3)=54+39+6}}}



{{{A(3)=99}}}



So the area is 99 square meters
