The length of a side of a square is given as 2x + 3. Which expression represents the perimeter of the square?
(a) 2x + 16
(b) 6x + 9
(c) 8x + 3
(d) 8x + 12

Solution:

Given, the length of a side of a square is 2x + 3.

We have to write an expression for the perimeter of the square.

Side = 2x + 3

Perimeter of square = 4(side)

= 4(2x+ 3)

= 8x + 12

Therefore, the perimeter is 8x + 12.

✦ Try This: The length of a side of a square is given as 3x. Which expression represents the perimeter of the square?

Given, the length of a side of a square is 3x.

We have to write an expression for the perimeter of the square.

Side = 3x

Perimeter of square = 4(side)

= 4(3x)

= 12x

Therefore, the perimeter is 12x.
