The perimeter of a pool table is 30 ft. The table is twice as long as it is wide. What is the length of the pool table?

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.

P = 2(L + W)

Half of 30 is 15.

Take it from there.

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.

To find the length of the pool table, we can set up an equation based on the given information.

Let's say the width of the pool table is "w" ft. Since the table is twice as long as it is wide, the length can be represented as "2w" ft.

The perimeter of the pool table is found by adding up all the sides. In this case, we have two lengths and two widths, so the equation for the perimeter is:

Perimeter = 2w + 2(2w)

Since the perimeter is given as 30 ft, we can set up the equation:

30 = 2w + 4w

Now we can solve for "w":

30 = 6w

Dividing both sides by 6 gives us:

w = 5

Therefore, the width of the pool table is 5 ft. Since the length is twice the width, the length of the pool table would be:

Length = 2w = 10 ft

So, the length of the pool table is 10 ft.
