Finding the Total Length of the Poster Edges

Lucy is making a poster for her school project, and she wants to measure the length of the poster she will create. She decides to make the poster 3 feet long and 2 feet wide.

What is the total length of the edges of the poster?

To find the total length of the edges, we calculate the perimeter of the rectangle using the formula:

$$P = 2 imes (length + width)$$
