Question 739588
given:

{{{A= 28000ft^2}}}

{{{L}}}-length
{{{W}}}-width

if {{{A= 28000ft^2}}}, then {{{L*W=28000ft^2}}}

if {{{L}}} is twice as long as it is {{{W}}}, then

{{{L=2W}}}..substitute in {{{L*W=28000ft^2}}} and solve for {{{W}}}

{{{2W*W=28000ft^2}}}

{{{2W^2=28000ft^2}}}

{{{W^2=28000ft^2/2}}}

{{{W^2=14000ft^2}}}

{{{W=sqrt(14000ft^2)}}}

{{{W=118.3216ft}}}


{{{L=2*118.3216ft}}}

{{{highlight(L=236.6432ft)}}}
