A=LW 192=(13+x)((9+x) 192=117+22x+x^2 (subtract 192 from both sides) x^2+22x-75+0 (factor) (x+25)(x-3)=0 so x=-25 or 3 Check work since we are adding x it can only be the positive solution so x=3 so the new dimensions are: L=13+3=16m W=9+3=12 check: 16*12=192 so the answer is correct hope this helped
