Given a parallelogram with the base of 4cm and the height of 3cm. Find the area of this parallelogram.
The picture below shows the parallelogram with the base of 4cm and the height of 3cm.
To calculate the area, we can start with the formula for the area of a parallelogram:
Since the base is given as 4cm, we can substitute b with 4. Similarly, since the height is given as 3cm, we can substitute h with 3. After doing so, we can calculate for A, as shown below:
Now, the calculated number 12 has no meaning unless we include the unit for it. Since the base is in cm, the unit for the area will be cm2. Hence:
Clearly, the answer is A.
