The perimeter is composed of two straight parts and two semicircles. We can use this to break down the problem.
We can find the straight parts easily. They are given in the problem.
straight parts: 82 x 2 = 164 m
The two semicircles make a circle. We just have to find the circumference of a circle with a diameter of 66 cm to get the length of the semicircles.
semicircles: 2(π)(66/2) = 66(3.14) = 207.24 m
answer: 164+207.24 = 371.24 m

Check the picture below.
so the perimeter of the kite is x+x+y+y, namely 2x + 2y.

Assume s is the side of the first square.
Let's find out the value of s:
4^2 = 2 × s^2 => s = 2.83 meters
Assume S is the side of the second square. Therefore 2.83^2 = 2 × S^2 => S = 2 meters.
The side of the second square is 2 meters
