Mark bought 168 meters of fencing to enclose an area of pasture for his sheep. he plans to use all of the fencing to make a rectangle that is twice as long as it is wide.

Your two equations are 2l+2w=114 and l=2w. To solve the system of equations, rewrite the second sentence as l-2w=0. Since the coefficients of w in the equations have opposite values, add the equations, and solve for l.

       2l+2w=114

    +      l-2w=0

           3l+0=114

                  l=38

So the answe would be 38 meters
