Question

If the perimator of the pool is 50m and the with is 10m how long is it

Answer 1

Step 1:

If the perimeter of a pool is 50 meters, that means that twice the width plus twice the length is equal to 50. This can be represented by the equation below:

`2w+2l=50`

Step 2:

If the width is 10, that means that twice the width is 20. We can plug it in and simplify:

`2(10) + 2l = 50`

`20 + 2l=50`

Step 3:

50 - 20 is 30. That means that twice the length is 30, as shown below:

`2l=30\\`

Step 4:

If twice the length is 30, then the length is 15.

Final Answer:

The length of the pool is 15m.
