Answer ( if trying to find x ) :
x = 44
Step-by-step explanation:
5 x 7 = 35 ( area of picture )
120 -> ( area of the whole picture + frame )
120 - 35 = 85 ( area of just the frame )
factor's of 85 -> 1 ,5 ,17 ,85 ( can't be 1 by 85 inch's picture ,so you get 5 by 17 )
5 + 5 + 17 + 17 = 44 (perimeter of the frame ( perimeter formula= l + l + w + w ) )
44 inch's ( ? )
