Step by Step Solution
Step 1
The picture below shows the trapezoid:
Step 2
To calculate the area, we can start with the formula for the area of a trapezoid:
Step 3
Since the parallel sides are given as 3cm and 5cm, we can substitute a with 3 and substitute b with 4. Similarly, since the height is given as 4cm, we can substitute h with 4. After doing so, we can calculate for A, as shown below:
Step 4
Now, the calculated number 16 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 = 16 cm2
Step 5
Clearly, the answer is A.
