Question 1137341
If the fence encloses the garden + border exactly, then
{{{ ( x + 4 )^2 = ( 37/4 )^2 }}}
Take the square root of both sides
{{{ x + 4 = 37/4 }}}
{{{ x = 9.25 - 4 }}}
{{{ x = 5.25 }}}
and
{{{ x + 4 = 9.25 }}}
The dimensions of the garden are 5.25' x 5.25'
---------------------------------------------------
check:
{{{ ( x + 4 )^2 = ( 37/4 )^2 }}}
{{{ 9.25^2 = 9.25^2 }}}
OK
