Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given information.
  • Step 2: Apply the formula for the area of a triangle.
  • Step 3: Solve for X X .

Now, let's work through each step:
Step 1: The problem provides the area of the triangle as 3 3 square units, with the base of the triangle as 2 2 units.
Step 2: The formula used for the area of a triangle is Area=12×base×height\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}.
Given that the base is 2 2 and the area is 3 3 , we rearrange to find X X (the height):

3=12×2×X 3 = \frac{1}{2} \times 2 \times X

Simplifying, we get:

3=X 3 = X

Therefore, the length of X X is 3 3 .
