## What is the mensuration explain Class 8?

Menstruation is the process of the shedding of the uterine lining on a regular monthly basis in women. During menstruation, the uterus wall along with blood vessels break off. This causes blood to come out and a new wall of the uterus is formed. Menstruation generally lasts for 4 to 5 days.

## What is 2D and 3D in mensuration?

Mensuration is the branch of mathematics which involves the geometrical shapes which may be 2D, 3D and their perimeter, area, surface area and volume with many of their measurements. The 2-dimensional shapes are those which are having only two parameters length and breadth.

**How is mensuration formula derived?**

Two Dimensional Figures

- Triangle. Perimeter (P) = a + b + c.
- Equilateral triangle. Perimeter = 3a.
- Right angled triangle. Area and h² = p² + b² (Pythagoras triplet)
- Rectangle. Area = Length × breadth.
- Square. Area = (side) ²
- Parallelogram. Area = base × height.
- Rhombus. Perimeter = 4 a.
- Irregular Quadrilateral.

**What are formulas in math?**
