00:01
So we're given a rectangular swimming pool that measures 30 feet by 14 feet.
00:06
So this black rectangle represents the original swimming pool.
00:10
We're told that we have a three foot, i guess, walkway or path that goes around the pool in every direction.
00:19
So the red represents that pathway.
00:22
And because it's three feet everywhere, that means this distance is three feet and this distance is three feet.
00:27
So that means the new length of with the walkway included is 36 feet.
00:34
In the opposite direction, this is three feet and so is this.
00:38
So that means that the new width of the entire pool, including the walkway, would be, let's see, 14 plus 6, 20 feet.
00:46
We're asked to find the total cost of tiling the walkway if it's $2 per square foot.
00:54
So we need to find the area of the walkway...
