triangle has height 12 and hypotenuse 13, so pythagoras gives the base of $\sqrt{13^2-12^2}=\sqrt{169-144}=\sqrt{25}=5$

anonymous · Answer

base is 5, height it 12, area of both triangles together is $5\times 12=60$ subtract that from the total area to get your answer

@skittles223   We may need to back up a step or 2, but I don't want to repeat any if you are already part way into this one.  What do you need help with to get started again?

anonymous · Answer

The total area of the square is Length times Width, right?  And since it's a square, both length and width are 12.
