Let's break this down step by step to find the total cost for Jack Robert's garden.
-
Identify dimensions:
- Length (L) = 5 yards
- Width (W) = 2 yards
-
Calculate the perimeter of the garden: The formula for the perimeter (P) of a rectangle is: \[ P = 2L + 2W \] Substituting the values into the formula: \[ P = 2(5) + 2(2) = 10 + 4 = 14 \text{ yards} \]
-
Calculate the cost for materials: The cost per yard for the materials is $7. Therefore, the total cost (C) can be calculated by multiplying the perimeter by the cost per yard: \[ C = P \times \text{cost per yard} = 14 \text{ yards} \times 7 \text{ dollars/yard} = 98 \text{ dollars} \]
So, the total cost for Jack Robert to put a fence around his garden is $98.
