Question

A bag of fertilizer covers 3000 square feet of lawn. Find how many bags of fertilizer should be purchased to cover a rectangular lawn 260 feet by 120 feet. *Round up to the nearest integer*

Answer 1

The first step is to find the area of the lawn. This can be done by multiplying its dimensions, so: 260 x 120. This equals 31,200.

Now to find how many bags of fertilizer are needed, divide 31,200 by 3000. This equals 10.4, but must be rounded up to 11 bags of fertilizer.
