Question

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

A)x + 4
B)x + 40
C)3x + 13
D)3x + 43

Answer 1

Option C would be correct.

Explanation:

A square has all equal sides; The perimeter is the sum of all the sides.

So all you have to do is divide the equation by 4 to et your answer...

12x/4 = 3x and 52/4 = 13

Answer 2

`3x + 13`

Explanation:

Perimeter: 12x + 52

Note: A square has four congruent sides

Since all four sides of a square are congruent, we'd divide the perimeter by 4:

`(12x+52)/(4)`

12/4 = 3x

52/4 = 13

Our answer would be 3x + 13
