Let's break down the question to its components.

It is a rectangular pool. It has four sides, with a length and width and the angles in corners being 90 degrees.

Let l be the length of the pool.
Let w be the width of the pool.

The perimeter of the pool is l + l + w + w or 2l + 2w

So 2l + 2w = 55 metres

You could make up a table for all the possible values, starting with a width of 1. 2(1) + 2w = 55
2 + 2w = 55
2w = 53
w = 53 /2

Good luck,

Paul

### How do i know how many cubic meter of concrete pour in 50 squre meter and 50m

as in any volume calculation, follow this formula:

a x b x h = volume
a x b = area
h = height
all dimensions must be in same units, if you use m, all must be m, if you use ft, all units must be ft, use decimal not inches in imperial measurement.

in your example you give area of 50m2, you did not give what thickness of the slab, or should i assume this is 50m thick slab?!?

### I have a Casio fx 82 MS and when i do calculations like 5/55 its giving me an answer of zero

Reset your calculator. If you choose an Exponential display format (Scientific, Engineering, Normal1, Normal2) select more decimal digits. Your current setting seems to display no decimal digits.

### Ratio examples

Assuming the floor is rectangular, the perimeter is 918 and the area is 50318. The ratio of these two numbers is 459:25159.

### Model FX-85GT PLUS- When dividing 55/21 the calculator will not produce the answer and instead will just show 55/21... What is the problem?

There isn't a problem per se. The calculator is simply showing you the result as an improper fraction.

Press the S--D key to toggle the result between symbolic and decimal forms. To have the results always come up in decimal, press SHIFT [SETUP] 2 to select the LineIO mode.

### When I enter 55/2 - the answer appears as a fraction. I would like for it to appear as a decimal. I know I can convert the answer using the SD key, but I would like the initial answer as a decimal.

To get the result in decimal format, press [SHIFT][=] instead of just [=].
You can also configure your calculator to show only decimal results:
1. Press [SHIFT][MODE] to access the (SETUP)
2. Select [2:LineIO]

### Polar/rectangular

For a TI-86

Converting rectangular to polar
Press "2ND" and then "MORE" for the MODE screen
Highlight PolarC and press "ENTER"
Quit that screen.
A example of converting 5+j6
Enter "(5,6)" in the calculator and press "ENTER"
Should get (7.81024967591*angle*50.1944289077)

Converting polar to rectangular
Press "2ND" and then "MORE" for the MODE screen
Highlight RectC and press "ENTER"
Quit that screen.
A example of converting 5*angle*35
Enter "(5*angle*35)
Should get (4.09576022145,2.86788218176)

Note
*angle* is the symbol when you press "2ND" then ","

Note 2
To round the an decimal places press "2ND" then "MORE" for the MODE screen and on the line that says float, choose a number on that line for the number of decimal places you would like to have.

### The perimeter of a rectangular field is 628 meters. The length of the field exceeds its width by 6 meters. What is the demensions.

Let x = the short side. Then the long side is the short side plus 6 meters
now we have 2 sides that are x meters long, add those together gives us 2x for the length
of both short sides

The length of the long side is x + 6 for one side and x + 6 for the other side. Added together we have x + 6 + x + 6 = 2x + 12

Adding the 4 sides together we get 2x ( the 2 short sides) + 2x + 12 (the long sides) we get 4x + 12 = the perimeter or 628. 4x + 12 = 628. Subtract 12 from both sides of the equation leaves 4x = 616. divide both sides by 4 leaves x = 154 So the width is 154 meters and the length is 160 meters.

Hope this helps

Good luck Loringh
