if 3 pounds of grass seed cover 403 square feet,how many pounds are needed for 5642 square feet?

5642/403 * 3

To find out how many pounds of grass seed are needed for 5642 square feet, you can set up a proportion using the information given.

Let's assume X represents the unknown number of pounds needed for 5642 square feet.

The given information tells us that 3 pounds of grass seed cover 403 square feet. So, we can set up the following proportion:

3 pounds / 403 square feet = X pounds / 5642 square feet

To solve for X, we can cross-multiply and then divide:

3 pounds * 5642 square feet = 403 square feet * X pounds

16926 = 403X

Now, divide both sides of the equation by 403 to isolate X:

16926 / 403 = X

The calculated value of X is approximately 42, which means approximately 42 pounds of grass seed are needed to cover 5642 square feet.
