a bag of fertilizer claims that it will cover 5000 square feet of grass if you front yard is 150 feet wide and 65 feet deep and you back yard is 150 feet wide and 225 feet deep how many bags of fertilizer will you need to fertilize your entire back yard?
A=A1+A2=(150*65) + (150*225)=43,500 Ft^2
43,500Ft^2 * 1bag/5000Ft^2=8.7 or 9 Bags
to cover both yards.
(150*225)Ft^2 * 1bag/5000Ft^2 = 6.75 or 7 Bags to cover back yard.
To find out how many bags of fertilizer you will need to fertilize your entire back yard, we need to calculate the area of your back yard and then divide it by the area that one bag of fertilizer can cover.
First, let's find the area of your back yard. The formula for finding the area of a rectangle is length multiplied by width.
Length of your back yard = 225 feet
Width of your back yard = 150 feet
Area of your back yard = Length × Width
= 225 feet × 150 feet
= 33750 square feet
Now, let's calculate how many bags of fertilizer you will need. Each bag can cover 5000 square feet of grass.
Number of bags needed = Area of back yard ÷ Area covered by one bag of fertilizer
= 33750 square feet ÷ 5000 square feet
= 6.75 bags
Since it is not possible to buy a fraction of a bag, you would need to round up to the nearest whole number. Therefore, you would need approximately 7 bags of fertilizer to fertilize your entire back yard.
