Question

The length of a rectangular field is 9m longer than its width, if the perimeter of the field is 270m find its width.​

Answers

  1. Answer:   63 meters

    ==================================================
    Work Shown:
    width = w
    length = w+9
    perimeter = 2*(length + width)
    P = 2(w+9+w)
    P = 2(2w+9)
    P = 4w+18
    4w+18 = P
    4w+18 = 270
    4w = 270 – 18
    4w = 252
    w = 252/4
    w = 63 meters is the width
    w+9 = 63+9 = 72 meters is the length
    Check:
    perimeter = 2*(length + width)
    perimeter = 2*(72 + 63)
    perimeter = 2*(135)
    perimeter = 270
    The answer is confirmed.
