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)

$A = l \times b$

2. Perimeter of a rectangle (P) = 2 × (Length(l) + Breath(b))

$P = 2 \times(l + b)$

3. Area of a square (A) = Length (l) × Length (l)

$A = l \times l$

4. Perimeter of a square (P) = 4 × Length (l)

$P = 4 \times l$

5. Area of a parallelogram(A) = Length(l) × Height(h)

$A = l \times h$

6. Perimeter of a parallelogram (P) = 2 × (length(l) + Breadth(b))

$P = 2 \times (l + b)$
