Question

The perimeter of a square is directly proportional to the length of its sides. a. write an equation to represent this direct variation. make sure to define your variables. b. in complete sentences, use a specific example to justify your equation from part a. include a drawing in your answer.

Answer 1

Explanation:

a. A square has 4 equal sides so the direct variation is

P = 4s where p = perimeter and s = length of each side.

b. If we have a square of side 3 the perimeter

p = 4s = 4*3

= 12.
