<u>Answer-</u>
<em>Strip with </em><em>2.13 ft </em><em>width can be used. </em>
<u>Solution-</u>
A club swimming pool is 21 ft wide and 41 ft long.
Hence, the perimeter of the swimming pool is

The club members want a uniform width border around the pool.
They have enough material for 264 ft²
As they will cover the perimeter of the rectangular pool, so the length of the total used strip is equal to the perimeter of the swimming pool.
Let the width of the strip is x ft
So, the total area of the used strip is,

Putting the values,



Therefore, strip with 2.13 ft width can be used.
we should save money to help others in need. i believe this because there are smart homeless kids out there who want and need an education. honestly do you want to be the person who gets a homeless person hooked on drugs because they don't have an education. and there are people with houses but they don't have the kind of money for college and if they do not get that scholarship. their life can take a turn for the worst. as for research 82% of people get hooked up on drugs because they lose their education an can not get a job. this can also lead to depression. that is one of strongest inside damage. it is worse than anxiety thats pretty bad. And it is also how people end up on the streets. And also giving money means study supplies and if thy study their education will most likely get better!!

Length of the base = 8
Length of the hypotenuse = 17

The length of the third side ''
".


Using Pythagoras theorem, we have
(Perpendicular)² + (Base)² = (Hypotenuse)²
+ (8)² = (17)²
+ 64 = 289
= 289 - 64
= 225
= 
= 
Therefore, the length of the missing side
is
.

(15)² + (8)² = (17)²
225 + 64 = 289
289 = 289
L.H.S. = R. H. S.
Hence verified.

5+3=8
