Can someone simply tell me what methods I must use in order to solve this word problem? Please, don't include the answer. I wish to solve this on my own. However, I would truly appreciate it if anyone could evaluate my answer afterwards.

"A rectangle has a width w and its length is 4 units longer than 2 times the width, or 2w + 4. Write a polynomial for the area of the rectangle."

  • Algebra 1 - ,

    L = 2 W + 4

    A = W * L

  • Algebra 1 - ,

    L = 2 W + 4


    A = W * L

    A = W * ( 2 W + 4 )

    A = 2 W ^ 2 + 4 W

    A = 2 ( W ^ 2 + 2 W )

  • Algebra 1 - ,

    Have you provided me with a method or the answer?

  • Algebra 1 - ,

    Both

  • Algebra 1 - ,

    Which is which?

  • Algebra 1 - ,

    Area of rectangle = width * length

  • Algebra 1 - ,

    So the answer is: A = 2w^2 + 4w?

  • Algebra 1 - ,

    A = W * L =

    W * ( 2 W + 4 ) =

    W * 2 W + W * 4 =

    2 W ^ 2 + 4 W =

    2 ( W ^ 2 + 4 W )

  • Algebra 1 - ,

    The answer is 2 ( W ^ 2 + 4 W )? I wouldn't simplify it?

  • Algebra 1 - ,

    A = 2 w ^ 2 + 4 w

    OR

    A = 2 ( w ^ 2 + 4 w )

    OR

    A = 2 w ( w + 4 )


    All three is same answer.

  • Algebra 1 - ,

    SORRY:


    A = 2 w ^ 2 + 4 w

    OR

    A = 2 ( w ^ 2 + 2 w )

    OR

    A = 2 w ( w + 2 )
