Understanding Perimeter and Area with Binomials

Mrs. Angel introduces the concept of binomials and their application in calculating the perimeter and area of rectangles. The lesson covers basic definitions and reviews how to calculate perimeter and area. Through examples, students learn to handle binomials in these calculations using methods like double distribute and the box method. The video concludes with a recap and a challenge problem for students to solve.
