Let 
represent the width of the frame. Since there is a frame around all four sides, there are two of these dimensions added to each of the length and width of the original picture, so the length with the frame is 
, and the width with the frame is 
, and since the total area is 180 inē:
(5\ +\ 2x)\ =\ 180)
Multiply it out, put the equation in standard form, and solve the quadratic for the positive value of . The negative root is discarded because a negative number for a measurement of length is nonsense.
