Math Expression: Area of a Parallelogram Practice Question

Given a parallelogram with the base of 4cm and the height of 3cm. Find the area of this parallelogram.

Step 1

The picture below shows the parallelogram with the base of 4cm and the height of 3cm.
Step 2

To calculate the area, we can start with the formula for the area of a parallelogram:
Step 3

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:
Step 4

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:

A = 12 cm²
Step 5

Clearly, the answer is A.
