P = 2(L + W)

Half of 30 is 15.

Take it from there.

perimeter is adding up all sides so x equals the width and 2x equals the length. x+x+2x+2x=30. so 6x=30, divide 30 by 6= 5, so x=5 which is the width and 2x=10 which is the length.

I don't get what l and w would be

P = 2(L + W)

30 = 2 (2W + W)

30 = 4W + 2W

30 = 6W

30/6 = W

5 = W

Now find the length.
