Answer:

42 cm²

Step-by-step explanation:

length of first parallel Side (a) = 8.5cm

length of second parallel Side (b) = 11.5cm

height (h) = 4.2cm

area of trapezium = ½ x ( a+ b ) x h

= ½ x ( 8.5 cm + 11.5 cm ) x 4.2cm

= ½ x 20 cm x 4.2cm

= 10cm x 4.2 cm

= 42cm²

Answer:

The area of trapezium=42cm^2

Step-by-step explanation:

Length of the two parallel sides= 8.5cm and 11.5cm

Sum of parallel sides=8.5+11.5= 20cm

Height= 4.2cm

Area of trapezium=½ x (sum of parallel sides) x h

                             =1/2 x (20) x 4.2

                             =10 x 4.2

                             = 42cm^2
