Tommy is planning to make a tomato garden. The rectangular garden must be 4 foot wide. Tommy doesn’t how long the garden will be, but would like 3 feet per tomato plant plus 1 foot extra at each end of the garden. Tommy doesn’t know how many tomato plants he will buy. The diagram below shows the dimensions of the garden for x amount of tomato plants. Create a simplified expression to represent both the area and perimeter of the garden.
