Answer:
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
