Answer:

$\large\red{\underline{\underline{\mathbb{SOLUTION}}}}$

Perimeter of trapezium = 104 m

Length of Non-parallel sides = 18 m and 22 m

Altitude = 16m

Area of Trapezium = ½ × (SUM of parallel sides)×altitude ------ (1)

Sum of parallel sides = Perimeter - (sum of non-parallel sides) = 104 m - (18+22)m = 104–40 m = 64 m

From (1), Area of Trapezium = 0.5×64×16 = 512 m²

Ans: Area of trapezium = 512 m²
