    the correct dimensions will solve both of these equations simultaneously, bh=12 , 2(b+h)=16 ie the dimensions will multiply to give twelve, and add to give 8

    let the lenth and breath of rectangle be l and b l x b = 12 l=12/b equation 1 and 2(l+b)=16 l+b=8 l=8-b equation2 eq1 = eq 2 12/b = 8-b 12=8b-b^2 b^2 -8b +12 = 0 (b-6)(b-2)=0 if b=6 l=2 if b=2 l=6
