# How do you find the perimeter of a complex figure?

Space and Astronomy## How do you find the perimeter of a complex shape?

Video quote: *We can find the perimeter of a rectangle by adding up all of the sides in this case eight plus six plus eight plus six or to make it slightly easier. We can add two of the sides eight.*

## How do you find the area and perimeter of a complex shape?

To calculate the perimeter of a polygon, add together the length of each side. For complex figures, **divide the figure into more recognizable parts.** **Then find the sum of the area of the parts**. When finding the perimeter of a complex region, be sure that the sum only includes the edges on the outside of the region.

## How do you find the perimeter of a figure?

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to **add the lengths of all the four sides**.

## How do you find the area of a complex figure?

To find the area of a composite figure or other irregular-shaped figure, **divide it into simple, nonoverlapping figures.** **Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure**.

## How do you do complex shapes?

Video quote: *One down here is pretty easy it's 6 by 4 this rectangle here so that's going to be 6 times 4 because area of a rectangle is length times width so 6 times 4.*

## What is the perimeter of composite figure?

Perimeter of Composite Figures

To find the perimeter of a composite two-dimensional figure, **add the lengths of the sides**.

## How do you find the perimeter of two shapes?

To find the perimeter, we simply **add up the lengths of each outside edge**. It may be helpful to look out for number bonds when adding the sides. For example, 7 + 3 = 10. The total of all of the outer sides is 36, so the perimeter is 36 cm.
