Final answer:
To find the number of bags needed to cover the rectangular yard, you need to divide the total area of the yard by the area covered by each bag of seeds.
Step-by-step explanation:
To find the area of the rectangular yard, you multiply the length by the width. In this case, the length is 22 m and the width is 14 m, so the area is 22 m x 14 m = 308 m². Each bag of seeds covers 18 m², so to find the number of bags needed, you divide the total area by the area covered by each bag: 308 m² ÷ 18 m² = 17.11 bags. Since you can't have a fraction of a bag, you would need to round up to the nearest whole number. Therefore, you would need 18 bags of seeds to cover the rectangular yard.
