Question 1102530
{{{system(w+L=210,cross((w-(2/5)w)+(L+(2/5)L)=210))}}}


System should be {{{system(w+L=210,(w-(2/5)w)+(L+(1/5)L)=210)}}}


-


{{{3w/5+6L/5=210}}}

{{{3w+6L=1050}}}

{{{3(210-L)+6L=1050}}}

{{{630-3L+6L=1050}}}

{{{3L=1050-630}}}

{{{L=140}}}{{{and}}}{{{w=70}}}, {{{original}}}{{{dimensions}}}




--------The following work and results are wrong-----------

{{{(3/5)w+(7/5)L=210}}}
{{{3w+7L=1050}}}
{{{3(210-L)+7L=1050}}}
{{{630-3L+7L=1050}}}
{{{4L=1050-630}}}
{{{4L=420}}}
{{{cross(L=105)}}}------------length of the ORIGINAL garden
-
{{{cross(w=105)}}}-----------width of the ORIGINAL garden

Question asks for the new garden; not for the original garden.

NEW garden dimensions:
{{{cross(126=L*1.20)}}}
-
{{{cross(63=w*0.60)}}}
