You are designing the garden of your dream and you are going to start with a blank canvas. That means killing everything before putting down new plants. To do this, you are going to use herbicide to kill the overgrown weed. You have a lot of land that measures 22.5 yard by 20.4 yard. Each bottle of herbicide holds 12 fluid oz (fl oz). The instruction says to mix 1.1 fl oz with 1.0 gallon of water and that will treat an area of 155 ft2. How many bottles of herbicide will you need

2.5 bottles or 3 bottles

Step-by-step explanation:

Given that :

Dimension of lot :

22.5 yds by 20.4 yds

Area of lot = 22.5 * 20.4 = 459 yd²

Volume per bottle of herbicide = 12 fl oz

1.1 fl oz combined with water treats an area of 155 ft²

Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90

1 yard² = 9 feet²

459 yard² = (459 * 9) = 4131 feet²

Number of 151 feet² that can be obtained from 4131 feet²

4131 feet² / 155 ft²

= 27.3576 times

= 27.3576 / 10.909

= 2.507

This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.
