The question is related to trigonometric ratio rule .
In the given diagram, there is a right angle triangle, with adjacent =57, and the unknown side is y. Given angle measurement is 39 .
To find the measurement of y, we will use tan rule which is


y = 57 tan 39 = 46.2
You would have to find the area of each side and add it all together if you were to solve it out it would be 45+25+32+25+35+35=394
