Finding Dimensions and Values in Geometry

This video tutorial helps students correct their homework for Section 6.2.5, covering problems 6-115 through 6-119. It includes instructions on sketching shapes, calculating perimeters for different values of X, ordering numbers, resizing shapes using ratios, and calculating the area and perimeter of a rectangle. Additionally, it guides students in finding approximate locations on a number line and coordinate plane.
