a=lw
w=l-3
therefore
a=(l-3)l
and a=4
therefore
4=l^2-3l
l=4(guess&check)
w=l-3
w=4-3
w=1
w=l-3
therefore
a=(l-3)l
and a=4
therefore
4=l^2-3l
l=4(guess&check)
w=l-3
w=4-3
w=1

L=-2
because...
a=lw
4=(1-3)L
4=-2L
divide both sides by -2
-2=L
because...
a=lw
4=(1-3)L
4=-2L
divide both sides by -2
-2=L
CLAUDIA
the length is l= -2
because area does equals length*width
which would be 4=(1-3)L
4=2L then you will have to divide both sides bby the negative 2
-2=L
because area does equals length*width
which would be 4=(1-3)L
4=2L then you will have to divide both sides bby the negative 2
-2=L
