Hi, now we are going to find how much will the custom walkway cost.
00:05
Now we have to draw the given information as a diagram.
00:12
Now, this is our pool with the dimension 30 by 15 feet and then this pool was surrounded by the custom walkway with the length of 5 feet.
00:32
So now the new length will be equal to 30 plus 10 that is equal to 40 feet and the new width will be equal to 15 plus 10 that is equal to 25 feet.
00:59
Now here the area of pool with walkway is equal to 40 multiplied by 25 that is equal to 1000 feet squared and the area of pool is equal to 30 multiplied by 15 that is 450 feet squared.
01:32
Then the area of walkway will be equal to 1000 minus 450 and this will be equal to 550 feet squared.
01:48
Now here the given cost per square feet is 27 .50 dollar.
01:58
Then the cost for 550 square feet will be equal to 550 multiplied by 27 .50 and this will be equal to 15 ,125 dollar.

So this is the answer for the first question and next in part b, we are going to find what is the area of the walkway in square yards...
