Answer:
10 square yard
Step-by-step explanation:
The area of the garden planted = area of the sector formed.
The radius of the garden = 4 yards
The area of the garden planted = 120° / 360° × π × 4^2
= 1/5 × 3.14 × 16
= 10.048 square yard
Therefore, the approximate area of her garden is 10 square yard
