the dimensions of a desktop are such that the length is 5 inches shorter than twice its width what expression describes the area of the desktop in terms of its width w ? (area of a rectangle=bh)

1 Answer

  • We know that to compute for the area of a rectangle, we can multiply the values of its length and width. Say we have a width of w, if the length of the desktop is 5 inches shorter than twice its width, then

    length = 2(w) - 5 = 2w - 5

    Given the dimensions, the area can be expressed as (length)(width) = w(2w-5) unitsĀ².

    Answer: w(2w -5) unitsĀ²
