Answer:
115 square feet.
Step-by-step explanation:
Please consider the complete question.
The Robertsons put a rectangular pool with a stone walkway around it in their backyard. The total length of the pool and walkway is 3 times the total width. The walkway is 2 ft wide all around. Find the area of the pool when the total width is 9 ft.
Let w represent width of pool.
Since total length of the pool and walkway is 3 times the total width, so total length of pool and walkaway would be .
Since walkway is 2 ft wide all around, so length and width of pool will be 4 feet less that is width would be and length would be
.
We know that area of rectangle is length times width, so we will get:
To find the area of pool, when total width is 9 ft, we will substitute in our area equation as:
Therefore, the area of pool would be 115 square feet.
