Let's denote the length of the poster as "L". We are given that the width is one-sixth the length, so we can express this relationship as:
Width = (1/6) * Length
We are also given that the width is 18 inches, so we can substitute this value into the equation:
18 = (1/6) * Length
To solve for the length, we can multiply both sides of the equation by 6:
6 * 18 = Length
Length = 108 inches
Therefore, the length of the poster is 108 inches.
Lauren has a rectangular poster of a puppy on her bedroom wall. The width is one-sixth the length of the picture. If the width is 18 inches, write and solve an equation to determine the length.
