Question

13) A hexagon has 6 equal sides! Ms. Sears asked the students to find the perimeter if all sides are equal to 2x + y. One student found the solution to be 18xy and another thinks it is 9xy. Is either solution correct? Show your work to justify your answer.

Answer 1

None of the answers are right

Explanation:

Since a hexagon has 6 sides, and perimeter is the length of all the sides summed up, we can multiply 6 by 2x+y to find the perimeter.

6(2x+y)

Distribute the 6 to each term in the parentheses:

6(2x)+6(y)

12x+6y is the perimeter. None of the answers are right.
