Question 1183421


given:
the yard dimensions
{{{ L=(11x-4) }}}
{{{W=6x width}}}


The shed is
{{{l= (3x+5) }}}
{{{w=4x}}}

1. Find the area of the yard.

{{{A[y]=L*W}}}
{{{A[y]=(11x-4) *6x}}}
{{{A[y]=66 x^2 - 24 x}}}


2. Find the area of the shed.

{{{A[s]=lw}}}
{{{A[s]=(3x+5)* 4x}}}
{{{A[s]=12x^2 + 20x}}}


3. Find the area of the lawn 

{{{A[lawn]=A[y]-A[s]}}}
{{{A[lawn]=66x^2 - 24x-(12x^2 + 20x)}}}
{{{A[lawn]=66x^2 - 24x-12x^2 - 20x}}}
{{{A[lawn]=54x^2 - 44x}}}
