Answer:
=  8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
; 
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm 
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
    h² = 8
h = √8 
   = √4√2
  = 2√2
Thus; 
Area = 1/2(3 +5) 2√2
          = 1/2 ×8 × 2√2
        <u>  = 8√2 cm² or  8sqrt2 cm²</u>
