I got 52a squared, I got the height of the triangle by reversing the area of a triangle thing (1/2 b x perpendicular height), and I got it to be something like 4. Then I used pythagoras theorem to find the hypotenuse which worked out as 7.2 and got the area of the triangle by l x w (all sides of a square are equal so its just 7.2 x 7.2 which is equal to 51.84, and I'm nearly sure you'd be expected to round it off to 52. And you would have to give it like 52a squared because thats what the question asked

It was very like the diagram of the proof of pythagoras theorem, I really wasn't expecting something with area or pythagoras theorem to come up on Paper 1 but I suppose I got through it :)
