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

because...

a=lw

4=(1-3)L

4=-2L

divide both sides by -2

-2=L

**CLAUDIA**, Monday, November 17, 2008 at 7:16pmthe 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
