Question 21947: Julia framed an oil painting that ther uncle gave her. The painting was 4 inches longer than it was wide, and it took 176 inches of frame molding. What were the dimensions of the picture? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! a) w + 4 = l
length is longer than width by 4"
b) 176" = 2w + 2l
this is the equation for the circumference
c) 176" = 2(l-4) + 2l
solve a) for w and substitute in b)
d) 176" = 2l - 8 + 2l
expanded
e) 184" = 4l
and 8 to both sides and combine terms
f) 46" = l
g) 42" = w
plugging l into a) and solving for w
