Answer:
Let x be the width of the rectangle, then the length is x + 10. The perimeter of the rectangle is 80 meters, so 2(x) + 2(x + 10) = 80.
Expanding and simplifying the equation gives 4x + 20 = 80, and solving for x gives x = 15.
So the width of the rectangle is 15 meters and the length is 15 + 10 = 25 meters.
