Is it possible?

I'm stumped, but I could be just stupid.

This isn't for my homework btw, I'm building a sub box for my car and fail at maths.

Cheers.

Supposing it's to scale, you could split it up into two shapes, find the area of the rectangle then find the area of the triangle.

Do you have the measurements for the top edge?

like, dur...

tan(70) = 400/x = answer

.5*answer*400= area triangle

400*(430-answer)= area square

area triangle+ area square = done
And what is more, there's been a bloody purple nose and some bloody purple clothes that were messing up the lobby floor. It's just apartment house rules so all you 'partment fools remember : one man's ceiling is another man's floor.

I would probably used to have some idea of doing it but I haven't done maths for about a year so I'm stumped. Just search for finding the area of an irregular quadrilateral into google.

It's not to scale, guys.

x=145,588

,5*145,588*400=29117,62

400*(430-145,588)=113764,76

29117,62+113764,76= about 142882,38 square millimeter

As Ex'sAndOh's said, find the flat bit on the top (technical I know), and it's easy enough.

I calculated it and i got 142910 mm^2= 14.2910 cm^2, which im pretty sure is right. PM me if you want proof or something.

EDIT: the guy above me is more accurate, cause i just rounded off the tan values.

Nearly the same as me.

Awesome, thanks guys, one more question though.

Seeing as you've worked out the area, what's the length of the top unknown value?....
