answer is 22 not 25 as question was How many “four-sided” figures appear in the diagram below? and in shape above we more than “four-sided” shapes.
Thanks for your comment Mahmoud, There are 25 unique 4 sided rectangle configurations in the diagram (marked in red).
Here is the summation method I used to arrive at this figure:
1’st row = 9
2’nd row = 9
3’rd row = 7
—————
Total = 25
hi how are 4-5-6-7-8-9 4 sided? looks like an error.
wow you’re *** bro it’s adding onto the diagram from before to keep track and in each row it starts over
