Question 1143611
Let the width = {{{ w }}}
The length is {{{ 2w }}}
-------------------------------
After the width is increased:
{{{ 2w = 1.5*( w + 2 ) }}}
{{{ 2w = 1.5w + 3 }}}
{{{ .5w = 3 }}}
{{{ w = 6 }}}
{{{ 2w = 12 }}}
the dimensions are 6 x 12
------------------------------
check:
Maria increases the width by 2ft 
The width is now 8ft
{{{ 1.5*8 = 12 }}}
OK
