With a knife scissors or anything else in that area!

Because otherwise you would have found the area of the rectangle/square (the rectangle/square being if you put two of the triangles together).

You cut the shape down into smaller shapes that you recognise and know how to calculate the area of. Then calculate the area of the small shapes and add the all up.

The formula to calculate the area of a triangle is 1/2 * base * height. To understand this, think of a rectangle or a square. To calculate the area of this object you would use length * width (which is the same as base * height). If you cut this object in half, you get a triangle. So that area of any triangle is 1/2 * base * height. I cannot answer your question because you are missing the triangle's height but you should be able to use the formula above to calculate the answer on your own.
