Question 1012944
hi dear,
The perimeter of the kite is {{{8sqart(2)}}} and the area is 8cm².
here is how to work it out.
since the kite is inscribed in a square of 4cm of which the edge of the kite is in the midpoint of the line that made up the square,note that this edge divides the line into 2cm by 2cm to make a total of 4cm.
use pythagoras theorem to find the sides of the kite which is 4root2,the add up the value for the sides of the kite to get 8root2.
for the area,use hero's formula to find that of a trianle,then....
