A bag of fertilizer covers 3000 square feet of lawn. Find how many bags of fertilizer should be purchased to cover a rectangular lawn 230 feet by 180 feet

14 bags

Step-by-step explanation:

Dimension of lawn : 230 feet by 180 feet

area of rectangle is given by length * width

Since lawn is rectangular area of lawn = 230 feet * 180 feet = 41,400 sq. feet

Given that one bag of fertilizer covers 3000 square feet of lawn.

Thus, to find no. of bags required to cover whole lawn will be

total area of lawn/area which one bag of fertilizer covers

no. of bags required to cover whole lawn = 41,400 sq. feet/3000 sq. feet

= 13.8 bags.

As no. of bags cannot be fractional, hence rounding bag to nearest unit place is 14 bags.
