Question

The sides of a square are equal in length. This means that the perimeter of a square is proportional to the length of one of its sides. A square with a side length of has a perimeter of .

Part 1 of 2
(a)Write an equation to represent the perimeter of a square where each side has length .

Answer 1

Perimeter = 4x

Explanation:

Let each side of the square be x in length. All sides have x length.

The preimeter of a square, P, is the sum of the lenghts of it's sides. Suince each side has length x, we can write:

P (Perimeter) = x + x + x + x

P = 4x
