The answer would be B. Area=base multiplied by the height. Turn the triangle into the square. Then you simply count the number of squares of the height to get 4. Then, count the number of squares of the base to get 3. 4 times 3 to get 12. NOW, there's one more step. Because the formula of the area of a triangle is base times height divided by 2, and since 12 is the area of the imaginary square, we have to turn it back into a triangle by dividing 12 by 2. This leads to a result of 6.
