Answer:
Step-by-step explanation:
A. Write an equation to represent this direct variation. Make sure to define your variables.
We define the variables:
P = perimeter
L = sides of the square
The equation that represents this proportional variation is:
P = 4L
B. In complete sentences, use a specific example to justify your equation from part A. Include a drawing in your answer.
Example: consider a square of sides 4 units. Find the perimeter.
The perimeter of the square can be found in two ways:
Way 1:
P = 4 + 4 + 4 + 4 = 16
Way 2:
Using equation of part A:
P = 4L
P = 4 * (4)
P = 16
