The minimum number of bags of seed the contractor needs to buy the to cover the entire lawn is 4
<h3>How to determine the number of bags</h3>
Start by calculating the area of the entire field using:
--- area of square
So, we have:


Next calculate the area of the porch using:
-- area of trapezium
So, we have:


The difference between the areas of the entire field and porch is the area of the lawn.
So, we have:


The above means that, the area of the lawn is 1940 square yards
If one bag of grass covers 600 square yards, then the number of bags that can cover 1940 square yards is:


Round to the next highest integer

Hence, the minimum number of bags of seed is 4 bags

Answer:
the correct answer is 1/2.
How i came to this answer was adding all of the number of medals together for all of the years, coming up to a total of 22. When asking about probability of any given set or amount of things, you always take the selected values and take them out of the whole amount. Years 2009 and 2012 have a whole selected value of 11 (4+7). Therefore you're "taking" 11 from 22, coming up with the fraction 11/22 seeing as that is not a answer choice the next step is to simply the fraction to 1/2.
