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
