For the area of a square, it is the base x the height, and the perimeter is 2height+2base. For the area of a triangle, it is base x height divided by two. And to find the perimeter you just add up each of the side lengths.

Perimeter and area can sometimes be found by applying simple Euclidean formulas that apply to various shapes such as circles, triangles, squares, etc. However, if you have very complicated shapes you may need more complicated forms of mathematical analysis, such as calculus.

The answer will depend on the shape. For simple shapes there are formulae which can be used to calculate the area and perimeter. For more complicated shapes it may be necessary to consider parts of the shape and measure their contribution to the area or perimeter of the overall shape and add these together.

What is the relationship for perimeter and area for rectangle?

There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter.
