Question 1153483
<br>
w = width; w+200 = length<br>
perimeter = 2(length+width)<br>
{{{2(w+(w+200)) = 1040}}}<br>
Solve using basic algebra....<br>
Without algebra....<br>
Imagine shortening the field by 200 feet, so that the length and width are the same.  That makes the perimeter 1040-400 = 640 feet.<br>
With length and width the same, the field is square; each side is one-quarter of the perimeter: 640/4 = 160.<br>
So the width of the field is 160 feet.<br>
Now add the 200 feet back on to the length to get 360 feet for the length.<br>
ANSWER: width 160 feet; length 360 feet<br>
