Answer 1

a.11 bags

Explanation:

Hello

I think i can help you with this

it is possible to solve this problem using a rule of three

Step 1

find the area of the of the rectangular lawn to cover

Area= length *width

Let

Length=410 feet

Width = 65 feet

Area=410 feet *65 feet

Area = 26650 square feet

Step 2

make the rule of three

1 bag of fertilizer ⇔ 2500 square feet

x? bags of fertilizer ⇔26650 square feet

isolating x

`(1 bag\ of\ fertilizer\ )/(2500 square feet)=(x)/(26650\ square\ feet) \\x=(1 bag\ of\ fertilizer\ *26650\ square\ feet\ )/(2500 square feet)\\x= 10.66\ bags\ of\ fertilizer\\`

0.66 bags can not be purchased, so 11 bags must be purchased

i hope it helps, have a fantastic day.

area of lawn: 410 x 65 = 26,650 square feet

26,650 / 2500 = 10.66

you will need 11 bags.
