    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
