Answer:

A=72CM^2

Step-by-step explanation:

The answer is 72cm^2 because the area of a triangle is h x b divided by two because the triangle is half of a square, since the square is side times side, the answer is 12x12 divided by two, wich is 144/2. The final answer is 72

Answer:

Step-by-step explanation:

area of a triangle = 1/2 × base length × height

base length = 12 and height = 12

so area = 1/2 × 12 × 12

==> multiply 12 by 12

area = 1/2 × 144

==> divide 144 by 2

area = 72
