Figures that can be subdivided into simple figures.
Dzanga-Sangha Complex of Protected Areas was created in 1990.
The areas are different.
yes
Because the surface areas of 3-d figures are two-dimensional and their measures require square units.Because the surface areas of 3-d figures are two-dimensional and their measures require square units.Because the surface areas of 3-d figures are two-dimensional and their measures require square units.Because the surface areas of 3-d figures are two-dimensional and their measures require square units.
Different figures have different formulae; here you will find formulae for the areas of some figures: http://en.wikipedia.org/wiki/Area#Formulae
When the can be added or subtracted evenly
It is the sum of the areas of each of its faces.
It will require many pages of a text-book to show the area- formulae for all figures.
Whatever the ratio of perimeters of the similar figures, the areas will be in the ratios squared. Examples: * if the figures have perimeters in a ratio of 1:2, their areas will have a ratio of 1²:2² = 1:4. * If the figures have perimeters in a ratio of 2:3, their areas will have a ratio of 2²:3² = 4:9.

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
