Hello, hello!As we're learning about the properties of polygons, we'll start with the area of polygons:
The area of a polygon is the quantity that expresses the extent of a shape. It is two-dimensional and is normally calculated by multiplying the length and the height of the shape.
The typical shape of rooms and other spaces are not just a rectangle or a square, so we'll need to add the areas of the shapes that compose them:
Other problem we may have is when the area we want to measure is a shape within another shape:
In this case, we need to subtract the area of the outside rectangle minus the area of the small one, in order to know the difference between them.
Area of a paralellogram
Paralellograms are always measured as if they were rectangles:
This is its formula:
Here you have a game to practice:
