-7n-15≤21. find n

❖ Add 15 to both sides:-
-7n≤21+15
-7n≤36
❖ Now divide by -7 on both sides:-
n≥-5.14 or
n≥-5
The inequality sign changed because we divided both sides by a negative number.

Based on the measurements of the pool and the path of uniform width, the area of the width and length of the path can be found to be 28.8 meters.
<h3>How to find the width and length?</h3>
First, find the area of the pool:
= Length x Width
= 10 x 26
= 260 meters ²
The area of the path can therefore be found to be:
= Total area of pool and path combined - Area of pool
= 1,092 - 260
= 832 meters²
Seeing as the path has uniform width, that means that the width is the same and the length so the width and length of the pool is:
= √area of the path
= √832
= 28.8
In conclusion, the width and length of the path are 28.8 meters.
