Answer:
The area of given trapezoid is 68.8 cm²
Step-by-step explanation:
Given: A trapezoid with height 6.4 cm and parallel base is 12.9 cm and 8.6 cm.
We have to find the area of area of this trapezoid.
Area of trapezoid = [tex]\frac{1}{2}\times \text{sum of parallel sides}\times height[/tex]
Given : Height = 6.4 cm
and parallel base is 12.9 cm and 8.6 cm.
Substitute, we have,
Area of trapezoid = [tex]\frac{1}{2}\times (12.9+8.6)\times 6.4[/tex]
Simplify, we have,
Area of trapezoid = [tex]\frac{1}{2}\times 21.5\times 6.4[/tex]
Area of trapezoid = 68.8 cm²
Thus, The area of given trapezoid is 68.8 cm²
