let


l = the length of the painting, l>0


w = the width of the painting, w>0


A large painting in the louvre museum in paris, france is 3 feet longer than it is wide:


l = w + 3


the wooden frame is 12 inches = 1 ft wide and the area of the picture and frame is 209 square feet:


(w + 2*1)(w + 2*1) = 209


plug l = w + 3 into the last equation:


(w + 3 + 2*12)(w + 2*12) = 209


by solving we find:


w = 12.46 ft
