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?

1 answer

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.
