Question

If the side of a square is 9x + 3 and x is a whole number, then the perimeter is a/an ____

• A. fraction
• B. prime number
• C. even number
• D. odd number

Answer 1

The correct option is C

even number

Perimeter of a square = 4 * side of a square

= 4 * (9x + 3)

= 36x + 12

Odd number * even number = even number

even number * even number = even number

4 - even number

9x + 3 - odd/even number

4 * (9x+3) - even number
