Separate the complex figure below into two rectangles to find the area. Use the formula of a rectangle which is Area = l × w. Then do the same with the other divided piece you cut. Add the sum of both areas and that will be your Area. For the perimeter, add all the numbers up and that's all. Hope it help :D
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
A binomial is an algebraic expression. It does not have an area.
by subtracting
Different figures have different formulae; here you will find formulae for the areas of some figures: http://en.wikipedia.org/wiki/Area#Formulae
the area and perimeter of the plane figures are square ,rectangle
You don't. You can find the area of geometric figures, not of numbers.
Different figures have different rules to determine the area of it.
Not easily. You need to find the area or perimeter of the components and sum them.
Figures that can be subdivided into simple figures.
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.

Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.
You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.
Try to decompose the figure into simple figures, for which formulae are known - such as triangles, rectangles, circular segments, etc.
