To evaluate the expression $ 7(l + 2w) $ for the given garden dimensions, we first need to substitute $ l = 5 $ yards and $ w = 2 $ yards into the expression. 1. Calculate $ 2w $: $$ 2w = 2 \times 2 = 4 $$ 2. Now substitute $ l $ and $ 2w $ into the expression: $$ l + 2w = 5 + 4 = 9 $$ 3. Now multiply this result by 7 to find the cost: $$ 7(l + 2w) = 7 \times 9 = 63 $$ Therefore, the cost for the garden is **$63**.
