The perimeter of a square newspaper ad is 40 centimeters. How long is each side?
Katyanochek1 [597]
The answer is:  "10 cm" .
____________________________________
Method 1)
____________________________________________
2L + 2w = 40 ;  Since the formula for perimeter of a rectangle (Note: a square is a rectangle) is:

                         P = 2L + 2w ;  Note:  L = length; w = width; P = perimeter;
______________________________________________________
 Factor out a "2":
_________________
" 2L + 2w = 40" ;

2 (L+ w) = 40;

Divide each side of the question by "2" ;
____________________________________
         [2 (L + w)] / 2  = 40 / 2 ;
____________________________________
 to get:  (L + w) = 20 ;

Note:  this "rectangle is a square" ; so L= w".
__________________
20 /2 = 10 ;

L + w = 10 + 10 = 20.

This is a square, so each side of the square is the same length.

Each side is:  10 cm .
______________________________________________
Method 2)
______________________________________________

We are given: The perimeter (sum of the lengths of all sides) of a square is "40 cm."  Since a square has 4 sides of equal length:
     Each side is:  40 cm / 4 = 10 cm.

if the speed of sound is 344 meters per second, what is the approximate speed of sound, in meters per hour?
choli [55]
Since we already know that the speed of sound is 344m per second, there are 60 seconds in one minute, and there are 60 minutes in one hour, we just multiply 344 by 60, giving us 20,640. Then we multiply 20,640 by 60 to get an answer of 1,238,400 meters per hour.
