**Finding the Area Formula of a Triangle**

*Review:*

**Giving the Area of a Parallelogram**

1) Ask pupil to create problems about finding the area of a parallelogram.

2) Teacher call the first player to read the problem he/she prepared. After reading he/she call one of his/her classmate to answer his/her problem.

3) If the answer is correct, the pupil gets a point, it's hi/her turn to call anyone to answer the question he/she prepared.

2. The formula in finding the area of a parallelogram. Area of a Parallelogram = Base x Height

3. A triangle is 2 of a parallelogram; therefore the formula in

finding the area of a triangle is to divide the product of the base and the height by 2.

**Area of a Parallelogram - A=bh**

**Area of a Triangle - A= 1/2 bh or bh/2**
