Area Math Example 3

Solution

1. 1
   Step 1: Recall the trapezoid area formula: $A = \frac{1}{2}(b_1 + b_2) \times h$, where $b_1$ and $b_2$ are the parallel sides and $h$ is the perpendicular distance between them.
2. 2
   Step 2: Substitute the given values: $A = \frac{1}{2}(8 + 12) \times 5 = \frac{1}{2}(20) \times 5$.
3. 3
   Step 3: Compute: $A = 10 \times 5 = 50$ cm².
