Answer:
6.2832 square units (rounded off to four decimal values)
Step-by-step explanation:
Area of a semicircle =  × π × r²
 × π × r²
r (radius) = 2 units
For our semicircle the area =  × π × 2² = 6.28318530718  square units
 × π × 2² = 6.28318530718  square units
Or 6.2832 square units (rounded off to four decimal values)
