(Originais Teachy 2024) - Question Easy of Mathematics

In the Science class, you learned about plants and drew a wooden planter to make your garden project. The planter has a shape similar to a rectangle and also to a square, and it has some edges where you will plant the flowers. To know how many little plants fit in each part of the planter, it is important to understand that where two wooden edges meet, they form an angle. Some of these angles are called right angles because they look like a lying 'L', and others are not right angles, meaning they do not look like an 'L'. By counting the right angles and non-right angles of the planter, you found out that there are 8 right angles and 4 non-right angles. With this information, you can determine what type of plant to put in each space of your planter. Now, tell the teacher how many spaces of the planter you have to plant flowers and describe how you found this out.
