poul has 124.8m of encing to build a rectangular pen. He wants the pen to have the largest possible area. Calculate the length and width of the pen to one decimal place.

I don't get it at all

  • Math7 -

    P = 2 L + 2W

    124.8 / 4 = 31.2

    The largest rectangular pen he can build is a square.
    (a square is a rectangle)

    so divide 124.8 by 4 to get the length of each side.
