Question

Please help if you can :)

Answer 1

a 32 sided polygon I believe

Answer 2

Here is your answer

$n= 32$

REASON:

$Concept used$: Sum of interior angles of a polygon=
(2n-4)×90 degrees , where n is no. of sides

So,

$(2n-4)×90= 5400$

$2n-4= 5400/90$

$2n-4= 60$

$2n= 60+4$

$2n= 64$

$n= 64/2$

$n= 32$
