Answer:
area = 26 m²
Step-by-step explanation:
4x5 = 20
3x4x0.5 = 7.5
20 + 6 = 26 m²
The area of the trapezoid is the amount of space on it, and the value of the area is 16.5 square cm
<h3>How to determine the area?</h3>
The given parameters are:
Parallel sides = 3cm and 8 cm
Height = 3cm
The area is then calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
So, we have:
Area = 0.5 * (3 + 8) * 3
Evaluate
Area = 16.5
Hence, the area of the trapezoid is 16.5 square cm
