Question

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

Answer 1

The side of the square is (12x+52)/4=3x+13.

Answer 2

The expression 3x+13 represents the side length of the square in units.

Explanation:

Let the a be the side length of the square in units.

The perimeter of a square is

`P=4a`

It is given that a square has a perimeter of 12x+52 units. Substitute P=12x+52 in the above formula, to find the expression that represents the side length of the square in units.

`12x+52=4a`

Divide both sides by 4.

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

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

`3x+13=a`

Therefore expression 3x+13 represents the side length of the square in units.
