We have the following:
the area of the triangle is given by the base and by the height of the triangle, in this case we are going to suppose that a square is a unit. therefore:
![\begin{gathered} A_A=(4\cdot5)/(2)=(20)/(2)=10 \\ A_B=(4\cdot5)/(2)=(20)/(2)=10 \\ A_C=(4\cdot5)/(2)=(20)/(2)=10 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/f0xaztx2wuu90e8rae94ir8yvpx3vtun10.png)
Which means that in reality the 3 triangles have the same area, although they are different, they present the same area
