Most commonly used formulas in mensuration:
Area of a rectangle: A = l × w,
- where l is the length and
- w is the width of the rectangle.
Area of a square: A = s^2,
- where s is the length of a side of the square.
Area of a triangle: A = (1/2) × b × h,
- where b is the base and
- h is the height of the triangle.
Perimeter of a rectangle: P = 2 (l + w),
- where l is the length and
- w is the width of the rectangle.
Perimeter of a square: P = 4s,
- where s is the length of a side of the square.
Volume of a cube: V = s^3,
- where s is the length of a side of the cube.
Volume of a rectangular prism: V = l × w × h,
- where l is the length,
- w is the width,
- and h is the height of the rectangular prism.
Volume of a sphere: V = (4/3)πr^3,
- where r is the radius of the sphere.
Surface area of a sphere: A = 4πr^2,
- where r is the radius of the sphere.
Circumference of a circle: C = 2πr,
- where r is the radius of the circle.
These are some of the basic formulas used in mensuration. There are many other formulas and concepts that are used in more advanced topics in geometry and mensuration.
