Question 1187640
----------------------------
rectangular playground has a walkway around it with a width of x-2.  The garden is 36 m by 20 m.  
Find an expression for the combined area of the playground and the walkway around it
--------------------------------


Length of the combined regions,  {{{2(x-2)+36}}};
Width of the combined regions, {{{2(x-2)+20}}};


The area,  {{{(2(x-2)+36)(2(x-2)+20)}}}, 

-

{{{(2(x-2)+2*18)(2(x-2)+2*10)}}}


{{{4((x-2)+18)((x-2)+10)}}}

{{{4(x+16)(x+8)}}}

{{{4(x^2+16x+8x+128)}}}

{{{4(x^2+24x+128)}}}

{{{highlight_green(4x^2+96x+512)}}}
