Final answer:
The height of the triangle is 2 cm.
Step-by-step explanation:
To find the height of a triangle, we need to use the formula: Area = 1/2 * base * height. Given that the area is 100 cm² and the base is 4 cm, we can rearrange the formula to find the height. 100 cm² = 1/2 * 4 cm * height. To solve for height, we divide both sides of the equation by 1/2 * 4 cm, which simplifies to 2 cm. Therefore, the height of the triangle is 2 cm.
