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.

Answer:
$64
Step-by-step explanation:
We have been given that a local food mart donates 20% of it's Friday's sales to charity.
This Friday the food mart had sales totaling 320.00 dollars.
To find the the amount donated to the charity, we will find 20% of $320.



Therefore, $64 were donated to the charity.
Answer: I think it would be 3.5
Step by Step Explanation: BRAINLIEST?!?
Answer:
what? i really dont understand
Step-by-step explanation:
To find the same value as 3 x 1/10 you first have to solve 3 x 1/10
so how to do this is you have to make 3 into a fraction
so to make 3 into a fraction you can put 3 as the numerator and 1 as the denominator
so you multiply

so 3/10 has the same value as 3x1/10
HOPE THIS HELPS!!!
