Area of section 1 is 8 square units which is triangle and,
Area of triangle is = 
b= 2 units and height =8 units
So,
Area of section 1 = 
Same Area is of section 2 which is also a triangle and has same base and height.
So,
Area of Section 2 =
Now the Area of section 3 which is square with side of 10 units
So,
Area of section 3 = 
Total Area of Trapezoid =
