Answer:
392 in^2
Explanation:
This is complicated, but not impossible!
First, remove the triangular shape at the bottom, secondly solve for the area of the square,
16.00 inches times 19.00 inches is 304.00 inches.
Secondly, subtract 19 from 30, leaving you with 11.
Multiply 11 by 16 = 176 then divide by 2, which is 88.
Add 88 to 304 which is 392.
Disclaimer - I cannot be entirely sure about my calculations.
