x = [?]

the must be 3 it couldn't be 10-x.

A = 6.1 units²

Step-by-step explanation:

Δ ABC and Δ A'B'C' are congruent, since the translation only shifts their position , but does not change their dimensions, then

AB = A'B' = 6.1

The area (A) of the triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 2 and h = 6.1 , then

A = × 2 × 6.1 = 1 × 6.1 = 6.1 units²
