You need to find the perimeter of one by adding together the lengths of all its sides. The perimeter of the similar shape is the answer multiplied by the similarity ratio.
by subtracting
To find the perimeter you add and to find the area we multiply.
In similar figures, any unit of area is proportional to the square of any linear measure. In this case, since the perimeter of the larger figure is twice as big, the area of the larger figure will be 4 times as big.
You can't. There are an infinite number of different figures that all have the same base but different heights.
Not easily. You need to find the area or perimeter of the components and sum them.

Break the composite shape down into simple units. Find the perimeter and area of each and then add these up as appropriate. If the shape cannot be broken down easily you may have to rely on integration or numerical methods.
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
You can't. There are an infinite number of different figures that all have the same base but different heights.
you divide the area by four and now you can find the perimeter
Perimeter = 2*Area/Apothem.
