Final answer:
The height of a triangle with an area of 3.6 cm² and a base of 6 cm is calculated using the area formula, resulting in a height of 1.2 cm.
Step-by-step explanation:
To find the height of a triangle when the area and base are known, we use the formula for the area of a triangle, which is area = 1/2 × base × height. The given area is 3.6 cm2, and the base is 6 cm. Rearranging the formula to solve for the height, we get height = (2 × area) / base.
Plugging the values in, we get height = (2 × 3.6 cm2) / 6 cm = 7.2 cm2 / 6 cm = 1.2 cm.
Thus, the height of the triangle is 1.2 cm, which corresponds to option B.
