    Good. Can you find for me the area of either one of the two triangles inside the square?

    Well, you should first use Pythagoras theorem to find the other side of the triangle, which would be \(\sqrt{13^2-12^2}=5\). Now the area of each triangle is \(1/2(12)(5)=30\).

    The area of the shaded portion is equal to the area of the square minus the area of the triangles. That's \(12^2-2(30)=84 m^2\)

    Use Pythagoras theorem. We have a side of the triangle equal to \(12\) and the hypotenuse is \(12\), so the third side is \(\sqrt{13^2-12^2}=5\).

    I meant the hypotenuse is \(13\).

    I think that you don't have enough information. Wouldn't you need to have the lenght of the shaded area first?

    2 triangles times 30 (the area of each)=60, and 12 times 12 is 144. Subtract the 60 from the 144 and you get 84.

    and the area of a triangle = 1/2 times the base times the height of the triangle.
