Question

A physical therapy facility is building a new pool that is 90 feet long and 5 feet deep. They have ordered enough tile for a 200-foot-long border around the edge. How wide should the pool be to ensure that all tiles are used?

Answer 1

Step-by-step explanation

We a are required to get how wide the pool should be to ensure that all tiles are used

To do so, we will have to set up some equations

Firstly, let the required width be w

Since the border is 200 feet long

And a rectangle has four sides in which opposite sides are equal

`90+90+w+w=200`

Solving for w

`\begin{gathered} 180+2w=200 \\ 2w=200-180 \\ 2w=20 \\ w=10\text{ feet} \end{gathered}`

Therefore

The border will be 10 feet on one side and 10 feet on the other side
