Answer:
The height of the trapezoid cross section is H = 4 ft
Step-by-step explanation:
From the figure
AB = 18 ft
CD = 8 ft
Area of the trapezoid = 52 [tex]ft^{2}[/tex]
We know that area of the trapezoid is given by
A = 0.5 × ( AB + BC ) × Height of the trapezoid ------ (1)
Put all the values in above formula we get
52 = 0.5 × ( 18 + 8 ) × H
H = 4 ft
Therefore the height of the trapezoid cross section is H = 4 ft
