A pool is 25ft by 15ft. fencing are sold in bundles. Each bundle provides 6ft of fencing. How many bundles need to buy?

Question

please help.

Answer 1

All right, for this problem you need to figure out the perimeter and then decide how much fencing is needed to cover all of it.

 

Start with the pool's dimensions: 25ft by 15ft. The perimeter would be the sum of all of its sides, so the amount that is needed to be fenced is 25+15+25+15 which is 80ft.

 

You know that the bundles are sold in 6ft bundles, so now you need to ask yourself how many 6ft bundles should I buy so that it is at least 80ft of fencing? In other words, how many times does 6 go into 80? Try to work out the math; keep in mind that you need at least 80ft of fencing so if your answer is not a whole number, round up!

 

I hope this helps!

Answer 2

I am assuming the pool is rectangular and that you are trying to determine the perimeter of the pool to see how much fence you need.

 

In this case, first start by figuring out the perimeter of the pool. 

The perimeter of a rectangle is P=(2L)+(2W) where L represents the length and W represents the width.

 

So, P=(2*25)+(2*15)=80 ft

 

Now that you know this lets look at the bundles of fence.

1 bundle=6ft of fence

 

If you need at least 80 ft of fence (the perimeter) to go around the whole pool then how many bundles do you need??

By doing 80/6 you can determine this.

 

80/6=13.3333 

 

Thus you need 13.3333 bundles of fence to have enough. The store doesn't sell 0.3333 of a bundle so,

 

You will need 14 bundles.
