Answer:
Area = 51 square units
Explanation:
Area of the figure given in the attachment = Area of a parallelogram ABEF + Area of a rectangle BCDE
Area of the parallelogram = Base × Height
 = AB × GE
 = 4 × 3 
 = 12 square unit
Area of rectangle BCDE = Length × Height
 = BC × CD
 = 
 [By Pythagoras theorem]
 = (√117) × (√13)
 = √1521
 = 39 square units
Now total area of the figure = 12 + 39 = 51 units²
