chap14 Perimeter , Area + Volume

1. Perimeter - Lenght around an object .

2. Area- Number of squares that fit into an object.

   • Area rectangle formula - A=lenght X width
     • Formula of triangle - A = 1/2base X perpendicular height
       • Formula Parallelogram - A= base X perpendicular height
         • Formula for disc - A= pie(2)h

3. Volume = amount of space an object occupies .

   • Formula cuboid - V=lenght X width X height
     • formula cylinder - V= pieR(2)h

4. Formula for surface area as well as volume A= 2(lenght X width + lenght X height + width x Height)
