Question

Use conversions to solve the problem. Jane wants to edge her garden with stone. All sides are equal. The stone costs ​$6 per yard. What is the perimeter of the​ garden? How much will it cost to buy the edging she ​needs?

Answer 1

Answer:

Perimeter: $p = 4\cdot l$, Total costs: $C = 24\cdot l$

Step-by-step explanation:

The garden has a square form. Let be $l$ the length of any of the sides, measured in yards. The perimeter of the garden, measured in yards, is:

$p = 4\cdot l$

Now, perimeter has a length unit and total costs of edging the garden, measured in US dollar, is:

$C = \left(6\,\frac{USD}{yard} \right)\cdot 4\cdot l$

$C = 24\cdot l$
