Question 242960
Hello, 
Let's represent the width as x and the length as 2x. From this we can set up an equation:
x + x +2x +2x = 240  Combine like terms will give us:
6x = 240  Divide 6 into both sides will be:
x = 40  Now we know the width is 40 meters and the length is 80 meters. Check this out by adding to see if it comes to 240 meters.
