width --- x m
length ---- x+12 m
2x + 2(x+12) = 104
easy from here, just solve for x, and back-substitute.
(oddly shaped athletic field , basketball-court is 28 m by 15 m, volleyball is 18 by 9, tennis 24 m by 11m etc
the perimeter of an athletic field is 104 meters and the length is 12 meters more than the width find the width and the length.
