2L + 2W = P
L + W = 1/2 * P
L = 1/2 * P - W
L = 1/2 * 274 - 56 = 137 - 56 = 81

The perimeter of a rectangular field is
P = 2*length + 2*width
We know that the perimeter P is 274 and the width is 56, so plugging in...
274 = 2*length + 2*56
274 = 2*length + 112
162 = 2*length
length = 81
Therefore the length is 81 yards

(274-2*56)/ 2 = length = 81 yards

Let length = L yards
(2 x 56) + 2L = 274
112 + 2L = 274
2L = 162
L = 81
Length = 81 yards

The perimeter is the distance around.....
twice the length plus twice the width... P=2l + 2w
P=274
w=56
Plug these values into the formula
P=2l + 2w
274=2l + 2(56) = 2l + 112
So, add -112 to both sides...
2l = 162
Think you can do the rest? Hint... multiply both sides by 1/2

274 = (2x56) + 2l
162 = 2l
81 = l
let l = length
