How do you find area and perimeter?

Answer 1

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.

Answer 2

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.

Answer 3

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.
