Answer: 9 cm
Step-by-step explanation:
Given area = 234 cm²
Parallel side, a = 20 cm
Parallel side, b = 32 cm
Height,h = ?
We know area of trapezium = 1/2 h x (a + b)
234 = 1/2 x h x (20 + 32)
234 = 1/2 x h x 52
234 = h x 26
234/26 = h
∴h = 9 cm
∴The height of the trapezium is 9 cm
Hope it helps you :)
