=Finding Surface Area and Volume=

__Figuring the Area and Perimeter of shapes__ Perimeter- In a closed plane figure the distance around the shape. Area- In a closed plane figure the number of squares in the shape. Postulate: The Sum of Areas- If there are two regions that do not over lap then the area is of the figure is the sum of the two reigons. Perimeter of a rectangle- b-base h- height P= 2b+2h Postulate: Area of a rectangle- b= base h= height A= bh

__Getting the areas of Paralleograms, Trapeziods, and Triangles__ Base of the triangle- Any side of the triangle can be the base of the triangle. Altitude of the triangle- Is a perpendicular segment going from the vertex of the triangle to the base of the triangle.
