7th grader math time!

The triangle m and n side length is equal.
The triangle k side lenght is a whole number and it is equal to the length of the first side (assuming m or n) squared.
Calculate the perimeter of the triangle.

Is this correct?
P = m + n + (n or m)^2

Yes, but I would guess that answer is expected to be written as:
P = 2*m + m^2
>>
I don't see a reason to use both m and n. It's better to use only one. But it's your choice to use either m or n.

n = m
k = m^2
P = k + m + n = m^2 + m + m = m(2 + m)
>>
yeah P=m(2+m)
