Question

You work for a landscaper that has a customer needing to seed an area of land 80 feet by 40 feet in size. The garden center has 5-pound bags of grass seed. Each bag of seed can cover 25 square yards of land. You calculate that the area you need to seed is 3200 square feet. You divide by 25 to find that you need 128 bags to seed the area. Is this correct?

Answer 1

Answer:

No, the solution discussed in question is not correct.

Step-by-step explanation:

Length of the garden ,l= 80 feet

Breadth of the garden ,b= 40 feet

Area of the rectangle = l × b

Area of the garden = A

$A=l\times b = 80 ft\times 40 ft = 3,200 ft^2$

Area covered by 1 bag of seeds of grass = $25 yard^2=225 ft^2$

$1 yard^2 = 9 ft^2$

Bags of seed of grass covering area of $3,200 ft^2$:

$\frac{3200 ft^2}{225 ft^2}=14.22$

14.22 bags of seed of grass will occupy the area covered by the garden.

Answer 2

You need to convert your 3200 sq ft into yards which is 355.556 sq yards then you divide 355.556 by 25 to get 14.22224 bags of seed needed
