Asked by Shapin
The Millers have hired an interior designer to decorate their family room. They want to have a 20" by 20" oil painting framed and incorporated in the design plan. If the designer chooses molding that is 4" wide and is priced at $2.10 per inch, how much will the molding cost (before tax)?

well, the perimeter of the painting is 20x20 inches
But the molding is 4" wide, so the outside length of the molding is 28x28.
So the cost is 4*28 inches * $2.10/inch = $___________

L = 4 + 20 + 4 = 28 in.
W = 4 + 20 + 4 = 28 in.
P = 2L + 2W = 2*28 + 2*28 = 112 1n.
Cost = 112in * 2.10/in. =
