FIRST PROBLEM AS GENIUS!!!

The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals [tex]x \sqrt{2} [/tex]. Using this, we can find that the height is 10. Take the average of the lengths to get l = 27. 

The area = 270. 
Should be 27, hope this helps!

Can I get a brainliest? I need it badly!
