Emma wants to put a lace ribbon around the edge of a rectangular table. The table has a length of $12\text{ cm}$ and a width of $8\text{ cm}$.How many centimeters of ribbon does Emma need in total?

Step 1: Identify the shape and required measurement

The problem asks for the total length of ribbon needed to go around the edge of a rectangular table. This means we need to find the perimeter of the rectangle.

Step 2: Recall the formula for the perimeter of a rectangle

The formula for the perimeter ($P$) of a rectangle is twice the sum of its length ($l$) and width ($w$).

Step 3: Substitute the given values into the formula

We are given the length $l = 12\text{ cm}$ and the width $w = 8\text{ cm}$. Substitute these values into the perimeter formula.

Step 4: Calculate the perimeter

First, add the length and width: $12\text{ cm} + 8\text{ cm} = 20\text{ cm}$. Then, multiply the sum by 2 to get the total perimeter, which is $40\text{ cm}$.
