you need two bottles of fertilizer for 42 feet perimeter. How many bottles do you need for a similar garden of 105 feet perimeter?

5 bottles 4 is 84 and 1 is 21

5bottles are needed

Step-by-step explanation:

If two bottles of fertilizer are needed for 42 feet perimeter, for 105perimeters, the number of fertilizers needed can be gotten using the law of equality as shown below;

2bottles = 42 feet perimeters

x bottles = 105feet perimeters

Cross multiplying to get the number of bottles 'x' we will have;

x bottles * 42feet perimeter = 2bottles * 105feet perimeter

x bottles = 2bottles*105ft perimeter/42ft perimeters

x = 210/42

x = 5bottles
