Answer:
428 square ft
Step-by-step explanation:
to do this you can break the shape up into multiple pieces
you can do it this way
the top left part of the polygon could be one shape
9 by 10
this is because if the left side is 23 and part of the left side is 13 the leftover part is 10
then the bottom is 13 by 26
then you multiply and add them together
(9 * 10) + (13 * 26) = 90 + 338
then you add
90 + 338 = 428
the answer is 428 square ft
