Area and Perimeter Concepts Review

The video tutorial covers a mixed review of area and perimeter calculations, aligned with IXL S13. It explains the difference between area and perimeter, and provides practice problems for calculating the area of squares, triangles, and circles, as well as the perimeter of rectangles and other shapes. The tutorial emphasizes using formulas and keeping answers in terms of pi where applicable. Students are encouraged to complete IXL exercises to reinforce their understanding.
