A square whose side is 10 cm, drawn two diagonals, find the area of the triangles.

We express the sought unknown area of each of the 4 triangles by means of the conditional variable “Y”.

Based on the data of such a problem and taking into account that the areas of each of the 4 triangles will be the same, we make the equation: Y = 10 x 10/4.

The result of the calculation looks like this Y = 100/4 = 25 cm ^ 2.

Answer: 25 cm ^ 2.
