@Kevin  help me first

kevin · Answer

perimeter and areas are differences right?
or it's same?

nvidiaintely · Answer

Its different.
Area is inside the shape lol.
And Perimeter is the outline I guess lol.

kevin · Answer

That's make me confused. lol
Since we don't know, what kind of polygon in the question

nvidiaintely · Answer

Ok.
Lets skip this for now.
I can get others help with  this.

kevin · Answer

sqrt(49):sqrt(16) = 22:n 
7 : 4 = 22/n
n = 12.57
