Basic Geometry Calculations

You will learn what perimeter, area, and volume actually describe, when each one matters in everyday life, and how to label measurements with the right kind of unit. By the end, you can look at a real situation and decide which measurement you need.

You’ll learn how to calculate the perimeter of common two-dimensional shapes and the circumference of circles using whole numbers and decimals. By the end, you’ll be able to determine total boundary lengths in practical situations like fencing, framing, edging, and measuring around circular objects.

You’ll learn how to calculate the area of squares, rectangles, triangles, circles, and composite shapes by breaking larger surfaces into simpler pieces. By the end, you’ll be able to determine how much tile, paint, or fabric a familiar surface requires.
