Given: L = 2w + 10

Since two of its sides are L long, and two are w long, the following equation is true:

2L + 2w = 128 m

Substituting for L:

2(2w + 10) + 2w = 128 m

Solving for w, we find w = 18 m.

Then substituting that back into our original equation:

L = 2(18) + 10 = 46 m

So the rectangle is 46 m long and 18 m wide.
