Question

The perimeter of a rectangular field is 354 yards. If the width of the field is 82 yards, what is its length?

Answer 1

2w + 2l = 354  where w = width and l = length 
so we have
2*82 + 2l = 354
2l = 254 - 2*82 =  190
l = 95

length is 95 yards

Answer 2

The perimeter is all the sides added up together.
So the width would be 82 and the side parallel is 82.
So 82+82= 164
Then subtract from the perimeter.
354-162 = 192
To find the width you divide 192 by 2.
The answer is 92 yards.
