Question

en with a perimeter of 105 feet? Item 9 You need two bottles of fertilizer to treat the flower garden shown. How many bottles do you need to treat a similar garden with a perimeter of 105 feet?

Answer 1

Answer:

5 bottles of fertilizer is needed to treat a similar garden with a perimeter of 105 feet.

Step-by-step explanation:

As, the figure is missing so below is the figure attached:

Given:

You need two bottles of fertilizer to treat the flower garden shown.

Now, to find the number of bottles to treat a similar garden with a perimeter of 105 feet.

So, getting the perimeter of the flower garden shown:

$4+18+5+15$

$=42\ ft.$

Thus, 42 feet perimeter garden need 2 bottles of fertilizer.

Let the number of bottles needed with garden perimeter 105 feet be $x.$

As given, 2 bottles of fertilizer is needed for 42 feet perimeter garden.

So, 42 is equivalent to 2.

Thus, 105 is equivalent to $x.$

Now, to solve by using cross multiplication method:

$\frac{42}{2} =\frac{105}{x}$

By cross multiplying we get:

$42x=210$

Dividing both sides by 42 we get:

$x=5.$

Therefore, 5 bottles of fertilizer is needed to treat a similar garden with a perimeter of 105 feet.
