Answer : The exact perimeter of kite UVWX is, 28 unit.
Step-by-step explanation :
First we have to determine the length UV by using pythagoras theorem.

Given:
OU = 3 unit
OV = 4 unit






Now we have to determine the length UX by using pythagoras theorem.

Given:
OU = 3 unit
OX = 9 unit






Now we have to determine the perimeter of kite UVWX.
Perimeter of kite UVWX = Sum of 4 sides
Perimeter of kite UVWX = Length UV + Length VW + Length XW + Length UX
As per image,
UV = VW = 5 unit
and,
UX = XW = 9.5 unit
Thus,
Perimeter of kite UVWX = 5 + 5 + 9.5 + 9.5
Perimeter of kite UVWX = 28 unit
Therefore, the exact perimeter of kite UVWX is, 28 unit.
