HSG.GPE.B.7: Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula.
What you'll learn
- Compute the perimeter of a polygon by summing the distances between consecutive vertices using the distance formula
- Compute the area of a rectangle in the coordinate plane using the lengths of its sides
- Compute the area of a triangle given the coordinates of its three vertices, using both the base-height method and the coordinate area formula
- Apply the Shoelace formula to compute the area of any simple polygon given its vertices in order
- Solve real-world and mathematical problems involving perimeters and areas of coordinate plane figures
