mathstudent55 · Answer

Do you mean the area of each triangle, or do you mean the sum of the areas of the two triangles?

For the area of each triangle, select a side to be the base and a side to be the height. You must know about base and height to know how to choose them. 
Then use the formula for the area of a triangle.

For the sum of the areas of the two triangles choose one of the methods below:
1) Follow the method above to find the area of one triangle, and then multiply the area by 2.
2) Put the two triangles together forming a rectangle, and find the area of the rectangle.
