Question about The Office Equipment & Supplies

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

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?!?

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.

The width is 96. Since this sounds like a homework problem, you'll have to show your work.

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.

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.

Now ready to go.

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.

Now ready to go.

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.

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
