Step by Step Solution

Step 1

The picture below shows the triangle with the base of 3cm and the height of 4cm.

Step 2

To calculate the area, we use the formula for the area of a triangle:

Step 3

Since the base is given as 3cm, we can substitute b with 3. Similarly, since the height is given as 4cm, we can substitute h with 3. After doing so, we can calculate for A, as shown below:

Step 4

Now, the calculated number 6 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:
