Final answer:
The width of the rectangle is 50 yards, and the length is 80 yards.
Step-by-step explanation:
Let's assume the width of the rectangle is x yards.
Since the length is 30 yards greater than the width, the length would be x + 30 yards.
The perimeter of a rectangle is the sum of all its sides, which can be calculated by adding the length and width and then multiplying by 2:
P = 2(x + x + 30) = 260
Simplifying the equation, we have: 4x + 60 = 260
Subtracting 60 from both sides: 4x = 200
Dividing by 4, we find: x = 50
Therefore, the width of the rectangle is 50 yards, and the length is 50 + 30 = 80 yards.
