Answer:
17
Explanation:
Since the 3 kites give 30
It means that 1 kite is 10
1 kite +2 circles give 20
It has already been discovered that 1 kite is 10 it means that one circle is 5
1 circle+2(2squares) give 13
And I circle is 5 it means that 1 (2square) is 4
So back to the question
1kite+1 circle+1(1 square)
10+5+2
17
The reason why the square is 2 is because it is 1( 1square) and not 1(2squares)
I hope you understand
The final answer is 17
