Answer:
4
Step-by-step explanation:
First we need to find the total area of the garden so we can see how many bags she will need. The area of a rectangle is its length multiplied by its width, so the area of her garden is 12 (the length) x 10 (the width). 12 x 10 = 120 square feet. If each bag covers 30 square feet, then she will need 120/30 = 4.
4 bags of fertilizer to cover the 120 square feet of the garden area.
