Part B: A 3-8 pound bag of fertilizer covers 1000 square feet Each bag costs $9.95 How many bags are needed to cover the garden? About how much it will it cost to buy the bags of fertilizer?

(The square ft of the garden is 1307.25)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

other answer is correct. i had used the radius of the radius somehow. a website:
