Final answer:
To replace a dead patch of grass measuring 4 feet by 11 feet, 44 square feet of sod are needed, calculated using the area formula for rectangles.
Step-by-step explanation:
The question appears to be a math problem with a typo involving 'sodium' that likely meant to refer to 'sod', which is a segment of grass used to repair or establish a lawn. To calculate the amount of sod needed to replace a dead patch of grass measuring 4 feet wide and 11 feet long, one would use the area formula of a rectangle, which is length × width.
In this case, the area would be 4 feet × 11 feet, yielding an area of 44 square feet. Therefore, 44 square feet of sod would be needed to replace the dead patch of grass.
In this case, we don't need sodium to replace the dead patch of grass. Sodium is an essential mineral for plants, but it is only needed in small quantities. Too much sodium can actually harm plants. The most important nutrients for plant growth are nitrogen, phosphorus, and potassium.
In order to help a dead patch of grass, you can focus on providing these essential nutrients. For example, you can use a fertilizer that has a balanced ratio of nitrogen, phosphorus, and potassium. You can also improve the soil quality by adding organic matter, such as compost, to promote healthy root growth and enhance water retention.
By addressing these factors, you can encourage the regrowth of grass in the dead patch without the need for sodium.
