Answer»

Step-by-step explanation:

Perimeter of TRAPEZIUM = 104 m

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

Altitude = 16m

AREA of Trapezium = 0.5 * (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 m^2

Ans: Area of trapezium = 512 m^2
