You can use this method when only the length of the diagonal is given and the other 2 sides are the same:
Treat this triangle as one quarter of a big square. If you can imagine or by drawing out, you will find that the big square has a length of 5 cm.
Area of the square is 25 cm2 and thus area of the triangle is 25 ÷ 4 = 6.25 cm2

One other restriction of this method is that it must be a right anglr triangle too
