Solution Steps

Step 1: Find the base of the triangle

The base of the triangle spans 4 squares on the grid. Since each square has a side length of 1 mm, the base of the triangle is 4 mm.

Step 2: Find the height of the triangle

The height of the triangle spans 3 squares on the grid. Since each square has a side length of 1 mm, the height of the triangle is 3 mm.

Step 3: Calculate the area

The area of a triangle is calculated as (1/2) * base * height. In this case, the area is (1/2) * 4 mm * 3 mm = 6 mm².

Final Answer:

Base: 4 mm Height: 3 mm Area: 6 mm²
