Subtract the area of the two triangles if you can.

3. skittles223

like can you just write out the problem for me

4. CliffSedge

The problem is already written out. I'm helping you write out the solution.

5. CliffSedge

Here's another hint: Pythagorean theorem will be useful.

6. skittles223

i mean the solution i got is area of square-2* area of triangle s*s-2*(1/2*b*h)=

|dw:1352400344997:dw||dw:1352400374373:dw||dw:1352400413251:dw| but the problem is that im not sure if the left/right side are also 12 since its not stated... but using geometry i think theres a way to prove they are since the shape inside fits and has a special property

10. Algebraic!

it is stated. it's a square.
