Question

Here is a garden and a pond.

Answer 1

Answer:

Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.

Step-by-step explanation:

You can observe a representation of this problem in the image attached.

Notice that the grass seed is gonna be put only in the green zone, out of the pond. So, we need to find each area and subtract them.

$A_{garden}= 14 \times 9 =126 \ m^{2} \\A_{pond}=2.4 \times 3.8 = 9.12 \ m^{2}$

The difference is

$A_{seed}=126 - 9.12 = 116.88 \ m^{2}$

Now, according to the problem, one box of grass seed covers 15 meters of the garden, let's divide this number with the seed area.

$n=\frac{116.88}{15} \approx 7.792$

Therefore, Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.
