a worker is usin boards to divide a rectangular animal pen into a row of 12 smaller goat pens. uhow many boards does the worker need?
Draw a picture of it. How many boards does the worker need?
It depends upon the width of the boards used. Let's assume they are as wide as the pen height needs to be (which is unlikely).
To divide the rectangle into a 4 x 3 array or 12 equal areas, five boards are needed. They will have to be notched where they intersect.

To determine the number of boards needed to divide a rectangular animal pen into a row of smaller goat pens, you first need to understand the layout of the pens. Let's assume the rectangular animal pen has a length of L and a width of W.
Since the worker wants to divide the animal pen into 12 smaller goat pens, they need 13 boards in total, including the boards on both ends of the row.
Here's how we can calculate the number of boards required:
1. Start with the number of goat pens minus one: 12 - 1 = 11.
This represents the number of dividing spaces between the pens.
2. Since each dividing space needs one board, the worker needs 11 boards.
3. However, they also need one board on each end of the row, bringing the total to:
11 (dividing spaces) + 2 (boards on ends) = 13 boards.
Therefore, the worker needs 13 boards to divide the rectangular animal pen into 12 smaller goat pens.
