Lesson 7.1A
M.3.G.2 Apply, using appropriate units, appropriate formulas (area, perimeter,
surface area, volume) to solve application problems involving polygons, prisms,
pyramids, cones, cylinders, spheres as well as composite figures, expressing solutions
in both exact and approximate forms
Perimeter
• Perimeter is:
the total distance around the outside
edge of a polygon.
• Find perimeter by: Adding all the sides
• Remember, when working with perimeter,
always give units!!!
