Mensuration is the branch of mathematics which deals with the study of Geometric shapes, their area, volume and related parameters.
Some important mensuration formulas are:
1. Area of rectangle (A) = length(l) × Breath(b)
2. Perimeter of a rectangle (P) = 2 × (Length(l) + Breath(b))
3. Area of a square (A) = Length (l) × Length (l)
4. Perimeter of a square (P) = 4 × Length (l)
5. Area of a parallelogram(A) = Length(l) × Height(h)
6. Perimeter of a parallelogram (P) = 2 × (length(l) + Breadth(b))
