L = length 
W= width
P= perimeter

L= w + 7 
since P=2L + 2W = 2(L+W) and P>62 
2(W + 7) + 2w > 62 
2W + 14 + 2w > 62 
4W + 14 > 62 
4W > 62 - 14 
4W > 48 
W > 48/4 
W > 12 
Therefore, the width is greater than than 12 mm

anonymous · Answer

Length = L   , Width = W , (L=W+7) since the length is longer than  the width by 7 mm               
Perimeter = 2L+2W  , substituting from previous equation , Perimeter =2W +14+2W=4W+14.    perimeter>62 , Then 4W+14>62  , 4W>48  ,W>12 , Same With Length (W=L-7) You Will Get 4L-14>62  L>19
