Do the information on a bag of fertilizer 5 pounds of fertilizer are needed for every two square feet of lawn how many square fe
gregori [183]

Answer:

25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.

Step-by-step explanation:

Given:

5 pounds of fertilizer cover = 2 ft^2 of the lawn

We need to find the 25 lb bag cover.

Solution:

Now we know that;

5 pounds of fertilizer = 2  ft^2 of yard.

1 lb of fertilizer = Number of ft^2 lawn covered by 1 lb fertilizer.

Using Unitary method we get;

Number of ft^2 lawn covered by 1 lb fertilizer = \frac{2}{5}\ ft^2

Now we can say that;

1 lb of fertilizer =  \frac{2}{5}\ ft^2 of the yard

25 lb of fertilizer = Number of ft^2 lawn covered by 25 lb fertilizer.

Again by using Unitary method we get;

Number of ft^2 lawn covered by 25 lb fertilizer. = \frac{2}{5}\times 25 = 10 \ ft^2

Hence 25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.
