Answer:
Equation: yard = 4w+8 = 208
width = 50 length = 54
Explanation:
yard = w + w + l + l
Since length = width + 4, replace the lengths with that.
yard = w + w + (w+4) + (w+4)
Simplify the right side.
yard = 4w+8
Replace "yard" with 208 because we know its perimeter is 208.
208 = 4w + 8
Subtract both sides by 8.
200=4w
Divide each side by 4.
50 = w
Conclusion: width = 50.
Since length = width + 4 and width =50, length = 54.
Hope this helps! :D
