I tried different ways of doing the equation but I still didn't get a correct answer
Im not sure if there is an equation.....
Anyways, we can first find the area of the square. That is 0.5^2, which is 0.25. The area of the triangles are 0.5(0.4)(2), which is 0.4. Add those together, and you get 0.65.
EDIT: THanks guest, i need to practice my addtion, lol
