Correct Answer - Option 1 : 128 m

^{2}
**Given:**

The length of the parallel sides of the trapezium is 12 m and 20 m

Distance between the parallel sides of the trapezium = 8 m

**Formula used:**

Area of a trapezium(A) = 1/2(Sum of parallel sides × distance between the parallel sides)

**Calculation:**

According to the question:

A = 1/2[(12 + 20)8]

⇒ A = 128

**∴ Area of the trapezium = 128 m**^{2}
