A rectangle on a grid is 6 units by 4 units. Cutting it along one
diagonal produces two congruent right triangles. What is the area
of ONE of those triangles?

24 square units, the same as the whole rectangle

12 square units, half of the rectangle's area

10 square units, the rectangle's area minus 14

20 square units, the rectangle's perimeter
