To find the cost of the fence around Mr. Rodriguez's vegetable garden, we first need to evaluate the expression \( 7(l + 2w) \).
Given:
- Length \( l = 5 \) yards
- Width \( w = 2 \) yards
Now, substitute the values into the expression:
-
Calculate \( l + 2w \): \[ l + 2w = 5 + 2(2) = 5 + 4 = 9 \]
-
Now, substitute this result into the cost expression: \[ 7(l + 2w) = 7(9) = 63 \]
Thus, the cost for the fence is $63.
The correct response is $63.
