given sides are 8.5cm and 11.5cm
and height = 4.2cm
so area of trapizum
=1/2*(sum of parallel sides)*height
=1/2*(11.5+8.5)*4.2
=1/2*20*4.2
=42cm square is ur answer
please pu me in brainlist

Answer:
42 cm²
Step-by-step explanation:
Length of the two parallel sides of a trapezium are 8.5 cm and 11.5 cm respectively and its height is 4.2 cm, find its area.
Area of a Trapezium = (1/2) (sum of Parallel side) * Height between parallel sides
Parallel sides are given as 8.5 cm & 11.5 cm
height is given as 4.2 cm
Area of Trapezium = (1/2) ( 8.5 + 11.5) * 4.2
=> Area of Trapezium = (1/2) (20) * 4.2
=> Area of Trapezium = 10 * 4.2
=> Area of Trapezium = 10 * 4.2 = 42 cm²
Area of Trapezium = 42 cm²
