Let's break down the problem step by step.

### Known Conditions:
1. Current patio area: $$ 600 \, \text{ft}^2 $$
2. Current length of the patio: $$ L = 30 \, \text{ft} $$
3. Current width of the patio: $$ W $$ can be calculated using the area formula $$ A = L \times W $$.

### Step 1: Calculate the Current Width
Using the area formula:
$$
A = L \times W \implies 600 = 30 \times W
$$
To find $$ W $$:
$$
W = \frac{600}{30} = 20 \, \text{ft}
$$

### Step 2: Determine the New Dimensions of Sam's Patio
(a) The new width is 3 times the current width:
$$
\text{New Width} = 3 \times W = 3 \times 20 = 60 \, \text{ft}
$$
The new length remains the same as the current length:
$$
\text{New Length} = L = 30 \, \text{ft}
$$

So, the new dimensions of Sam's patio are:
- New Length: $$ 30 \, \text{ft} $$
- New Width: $$ 60 \, \text{ft} $$

### Step 3: Calculate the Area of the New Patio
The area of the new patio can be calculated as:
$$
\text{New Area} = \text{New Length} \times \text{New Width} = 30 \times 60
$$

Let's calculate this area:
$$
\text{New Area} = 1800 \, \text{ft}^2
$$

(b) To find how the expansion changes the area of the patio:
$$
\text{Area Change Factor} = \frac{\text{New Area}}{\text{Current Area}} = \frac{1800}{600} = 3
$$

### Step 4: Advice for Lisa's Patio Expansion
(c) Lisa wants to make her new length 7 times the current length and make the new width the same as the current width.

Let’s denote Lisa's current length as $$ L_L $$ and current width as $$ W_L $$. The new dimensions will be:
- New Length: $$ 7 \times L_L $$
- New Width: $$ W_L $$

The area of Lisa's new patio will be:
$$
\text{New Area}_L = (7 \times L_L) \times W_L = 7 \times (L_L \times W_L) = 7 \times \text{Current Area}_L
$$

Thus, the area of Lisa's new patio will be $$ 7 $$ times the area of her current patio.

### Summary of Answers:
(a) New Length: $$ 30 \, \text{ft} $$, New Width: $$ 60 \, \text{ft} $$  
(b) The area of the new patio will be $$ 3 $$ times the area of the current patio.  
(c) The area of Lisa's new patio will be $$ 7 $$ times the area of her current patio.
(a) New Length: 30 ft, New Width: 60 ft (b) The area of the new patio will be 3 times the current area. (c) The area of Lisa's new patio will be 7 times her current patio area.
