Answer:
6.1 square units
Explanation:
Since the triangle was translated from one position to another position, the dimensions of the triangle have not changed. The pre-image and image are congruent.
area = base * height/2
The two sides forming a right angle can be used as the base and the height in the area formula.
BC = base = 2
AB = A'B' = height = 6.1
area = 2 * 6.1/2
area = 6.1 square units
