Answer:
12 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 4 ( perpendicular distance between the bases ) and
b₁ = SR = 2, b₂ = TA = 4 , then
A =
× 4 × (2 + 4) = 2 × 6 = 12 units²
