Allright so I am doing my math assignment and I don't know if this is right or not.

Area of the big blue square: 98.654 squared - aprox 9763.61

Area of triangle is 1/2bh= 1/2(45.5)(55.5) = 1262.625

I added the area of triangle to area of square = 1262.625+9763.61=11026.325

So the answer i got is 11026.325 ???

Please help!
