The formula for perimeter is:
P = 2l + 2w
Substitute:
P = 2(7.28) + 2(12.42)
= 14.56 + 24.84
= 39.70 yards

For a fence, you need twice the width and twice the length (draw a picture and you'll see pretty quickly). So 2*7.28 + 2*12.42 or, if easier 2 * (7.28 + 12.42) or 2 * (19.7) = 39.4 yards

You want the distance around the field. That's called the perimeter. length + width + length + width
Or, 2 L + 2W
2 X 7.28 + 2 X 12.42 , =14.56+24.84 = 39.4 yards

2(7.28 + 12.42) yds
2 x 19.7 yds
39.4 yds must be purchased.

p=2(width+length)
p=2(7.28+12.42)=39.40
