To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
multiply and divide by 2
count the grids
You find perimeter by adding all the sides of a figure.
All you do is add up all the sides to find the perimeter even though it is a odd shape

To find the distance around the shape
count the grids
You find perimeter by adding all the sides of a figure.
There are many formulas for perimeter depending on what shape you are trying to find the perimeter of. The perimeter is the distance around a shape, so one formula to find perimeter is simply adding all the side lengths together.

how can you find the perimeter of a cone i.e. a 3d shape!
Perimeter = The sum of the lengths of all sides of a shape
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
