The trapezoid below has an area of 475 square meters.
OLga [1]
Data:
B (Larger base) = 28 m
b (Minor base) = 18 m
h (height) = ?
A (area) = 475 m²

Formula:
A =  \frac{(B+b)*h}{2}

Substitute:
475 = \frac{(28+18)*h}{2}
475 = \frac{\diagup\!\!\!\!\!46^{23}*h}{\diagup\!\!\!\!2^1}\:\:\to\:\:\:475 = 23*h\:\:or\:\:\boxed{\boxed{23h = 475}}

Answer:
\textcircled{ A }  23h = 475
