how do we find surface area and lateral area of pyramids and cones
pyramids are a soild that connects a polygon base to a point

the lateral area formula is perimeter mulipied by the length divided by two.
the surface area is the lateral area pluse the base.

how do we identify soilds?

     soilds have properties like
volume
surface area

    there are two main types of soilds
polyhdra-must have flat faces( prismsa,pyamids,platonic soilds)

how do we solve compound area problems?

by braking up the figure into little figues you remember like squares, triangles and rectangles and using there area formulas

how do we find the area of a circle?
formula is or

Here is an example:

Example 1:	how do we calculate the area of paralleograms,kites and trapizoids? Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters.
Solution:
	= (12 cm) · (5 cm)
	= 60 cm2 Find the area of the following kite. the formula is d1 mulpiplied by d2 divided by 2 The area of a trapezoid is given by the formula where b1, b2 are the lengths of each base h is the altitude (height)

Example 1:	Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters.
Solution:
	= (12 cm) · (5 cm)
	= 60 cm2 Example 1: Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters. Solution: = (12 cm) · (5 cm) = 60 cm2 The area of a trapezoid is given by the formula where b1, b2 are the lengths of each base h is the altitude (height)

how do we calculate the area of a rectangle and a triangle?
the area of a rectangle is found by the formula 
Area =length multiplied by the withe
the area of a triangle is found by the formula
Area= one half base multiplied by height (base multiplied by  height over two)
