They say that the length is 5 inches longer than the width, then We know So, putting it all together: We know our width is 7. Plug it back into w+5 =l. Our length is 12. So our dimensions are 12 x 7. Let's check this to make sure. They say the perimeter is 38, then 12(2) + 7(2) better = 38. 24 + 14 = 38. Check. Hope this helps!
