# Mensuration

## Mensuration Formulas:

**1. Rectangle**

Area = lb

Perimeter = 2(l+b)

**2. Square**

Area = a2

Perimeter = 4a

**3. Parallelogram**

Area = bh

Perimeter = 2(a+b)

**4. Triangle**

Area =bh/2

**5. Right angle Triangle**

Area =1/2(bh)

Perimeter = b+h+d

**6. Isosceles Right Angle Triangle**

Area = 1/2. a2

Perimeter = 2a+d

**7. Trapezium**

Area = 1/2h(a+b)

Perimeter = Sum of all sides

**8. Rhombus**

Area = d1d2/2

Perimeter = 4l

**9. Quadrilateral**

Area =1/2 Diagonal (Sum of offsets)

**10. Kite**

Area = d1d2/2

Perimeter = 2 Sum on non-adjacent sides
