What is the formula for different shapes? (Triangles, squares, ect..)

Answer 1

Here are some common formulas for different shapes:

- Triangle:
- Area = (base x height) / 2
- Perimeter = sum of all sides

- Square:
- Area = side x side
- Perimeter = 4 x side

- Rectangle:
- Area = length x width
- Perimeter = 2 x (length + width)

- Circle:
- Area = π x radius^2
- Circumference = 2 x π x radius

- Trapezoid:
- Area = ((base1 + base2) / 2) x height
- Perimeter = sum of all sides

Note: π (pi) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter, approximately equal to 3.14159.
