I'll draw a diagram for you, so that it's easier to understand.
First you have to understand that the perimeter is all the sides add up together.
Let's set up an equation, using l for the length, and w for the width.
5w + w = 48
Simplify
6w = 48
Divide by 6 on both sides
w = 8
Now the value we got is actually both widths (the green sides), so the width is actually 4. Which means that the length is 20.
The answer is
4ft by 20 ft.Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Answer:
Total cost = <em>$</em> 4.55
Step-by-step explanation:
2(8a + 5b) -(2a + 3b)
<em>Part A: Simplify the expression shown above</em>
Exapanding the brackets;
16a + 10b - 2a - 3b
Collecting like terms;
16a - 2a + 10b - 3b
14a + 7b
<em>Part B: If a represents apples that cost $0.25 each and b represents bananas that cost SO. 15 each, what is the total cost based on the expression above?</em>
a = 0.25
b = 0.15
14a + 7b
Inserting the values into the equation;
14 (0.25) + 7(0.15)
Total cost = <em>$</em> 4.55
