Answer:
h = 6 cm
Step-by-step explanation:
Given that,
The area of a trapezoid, A = 66 cm²
The sum of the lengths of the two bases of a trapezoid is 22 cm.
We need to find the height of the trapezoid.
The area of a trapezium is given by :
[tex]A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}[/tex]
Substitute the values,
[tex]h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm[/tex]
So, the height of the trapezoid 6 cm.
