you are making a fence of your garden the length is five less than two times the width write a polynomial that represents the perimeter of the garden write a polynomial that represents the area of the garden

Now you can take the time to reread and understand the question.

What is the length if the width is x?

Take the sentence
"length is five less than two times the width" and replace the word "width" by x (that we defined above), and translate it to mathematics.

Put x = width of the garden

then what would be the length in terms of x?

i put x width of the garden now i don't know what to do

The width would be x and the length would be 2x-5?

i draw a picture

now what i do??

First--how did you try to solve the problem? If you do not know where to start, I suggest you draw a picture of the fence and then write down what you know about each side.
