## Measurement Formula :

Measurement formula is Area of a Triangle_{(sq.u)} in square units is equal to the Base_{(kg/m/A/K)} in kilogram and meter and Ampere and Kelvin and multiply by the Height_{(m) } in meter divided by 2.Hence the measurement formula can be written as

Area of a Triangle_{(sq.u)}=Base_{(kg/m/A/K)} * Height_{(m)}/2

Distance= √(x_{2}-x_{1})^{2}+(y_{2} –y_{1})^{2}

circumference of a circle =2 πr

## Sample Problems :

### Example1 :

Calculate the area of a triangle with base 5 units and height 9 units?

### Solution :

Base=5unit

Height=9unit

Area of a Triangle=fraction Base * Height2

=frac5*92

=frac460

=23sq.units

### Example2 :

Calculate the distance between two points (3, 4) and (7, 5)?

### Solution :

(x_{1,}y_{1})=(3,4)

(x_{2,}y_{2})=(7,5)

Distance between the points=√(x_{2}-x_{1})^{2}+(y_{2} –y_{1})^{2}

=√(7-3)^{2}+(5 –4)^{2}

=√(4)^{2}+(1)^{2}

=4units
