Given,
b1 = Formation width
h = Height of the embankment
S:1 = Side slope of the embankment (H: V)
The area of embankment = The area of the trapezium
Area of Trapezium = \(\frac{1}{2}\) × (Sum of Lengths of parallel sides) × Height
Area of Embankment 1 \(= \frac{1}{2}\left[ {b_1 + \left( {b_1 + 2sh} \right)} \right] \times h\)
A1 = b1h + sh2
Similarly the area of embankment 2 = A2 = \(= \frac{1}{2}\left[ {b_2 + \left( {b_2 + 2sh} \right)} \right] \times h\) = b2h + sh2
Total area = A1 + A2 = b1h + sh2 + b2h + sh2 = (b1 + b2) h + 2sh2
