Question 842222
The area of the garden is:
{{{ 27x }}}
The area of the garden plus the sidewalk is:
{{{ ( 27 + 6 + 6 )*( x + 6 + 6 ) }}}
{{{ ( 27 + 12 )*( x + 12 ) }}}
{{{ 39x + 468 }}}
-----------------
The area of the sidewalk is:
{{{ A = ( 39x + 486 ) - ( 27x ) }}}
{{{ A = 39x - 27x + 486 }}}
{{{ A = 12x + 486 }}}
Cost to build sidewalk = ( area in sq ft ) x ( cost/ sq ft )
{{{ C = ( 12x + 486 )*92 }}}
{{{ C = 1104x  + 44712 }}}
