Please explain how to set this up and how to solve:

A school's rectangular athletic fields currently have a length of 125 yd and a width of 75 yd. the school plans to expand both the length and the width of the fields by x yards. What polynomial is standard form represents the area of the expanded athletic field?

  • math -

    A = Area

    L = Lenght

    W = Width


    New lenght L = 125 + x

    New width W = 75 + x


    A = W * L

    A = ( 125 + x ) * ( 75 + x )

    A = 75 * 125 + 75 * x + x * 125 + x * x

    A = 9375 + 75 x + 125 x + x ^ 2


    A = x ^ 2 + 200 x + 9375

  • math -

    (x+125)(x+75) = Area

    I loved the way you broke it down and explained it to me in detail. What a great help!
