A 25-lb bag of grass seed will cover 1200 square feet. If tour lawn is in the shape of a rectangle and measures 205 feet by 145 feet, how many bags of grass seed will you need to cover the lawn?
how do i solve?
A = bh/2
A = (205 * 145) 2
A = 14,862.5
14,862.5 / 1,200 = _______ bags
bags=area/1200=205*145/1200
To solve this problem, you need to calculate the total area of your lawn and then determine how many bags of grass seed are required to cover that area.
Step 1: Calculate the area of the lawn:
Area = Length × Width
Area = 205 feet × 145 feet
Area = 29725 square feet
Step 2: Determine the number of bags needed:
Since one 25-lb bag of grass seed can cover 1200 square feet,
Number of bags needed = Total area ÷ Area covered by one bag
Number of bags needed = 29725 square feet ÷ 1200 square feet
Now, let's calculate the number of bags needed:
Number of bags needed = 24.77 bags (rounded to the nearest whole number)
Therefore, you will need approximately 25 bags of grass seed to cover your lawn.
To solve this problem, you need to calculate the area of your rectangular lawn and then determine how many bags of grass seed are needed to cover that area.
1. Calculate the area of your rectangular lawn: The formula for calculating the area of a rectangle is A = length x width. In this case, the length is 205 feet and the width is 145 feet. So, the calculation is A = 205 feet x 145 feet = 29,725 square feet.
2. Determine how many bags of grass seed are needed: You know that one 25-lb bag of grass seed covers an area of 1200 square feet. Therefore, to find out how many bags are needed to cover 29,725 square feet, you can divide the total area of the lawn by the area covered by one bag:
Bags needed = Total area of lawn ÷ Area covered by one bag
Bags needed = 29,725 square feet ÷ 1200 square feet
Bags needed ≈ 24.77 (rounded to two decimal places).
Since you cannot purchase a fraction of a bag, you will need to round up to the nearest whole number. Therefore, 25 bags will be needed to cover the lawn.
So, to cover the lawn measuring 205 feet by 145 feet, you will need 25 bags of grass seed.
