Calculating the Area of Shapes

Guided Notes

3 key concepts

  • 1

    Area is expressed in square units, such as meters squared, because it measures the amount of surface a figure covers.

  • 2

    The area of a parallelogram is found by multiplying the base by the height, which is similar to finding the area of a rectangle.

  • 3

    To find the area of irregular shapes, you can break them into simpler shapes like rectangles, triangles, and semicircles, then add the individual areas together.
