Final answer:
Assuming the '3m' is the radius of a circle, the area is calculated as A = πr², resulting in an area of 9π square meters.
Step-by-step explanation:
The question seems to be missing key information such as the shape or dimensions required to find the area. However, assuming the '3m' mentioned refers to the radius of a circle, we can use the formula for the area of a circle, which is A = πr². To find the area, you would square the radius (3m × 3m = 9m²) and then multiply by π (3.14 or 22/7). Therefore, the area of the circle would be 9 × π square meters, which could be expressed as 9π when π is approximated by 3.14 or 22/7. This corresponds to option (a) 9π square meters.
