Area = |(0×0 + 8×6 + 3×0) - (0×8 + 0×3 + 6×0)| / 2 = |(0 + 48 + 0) - (0 + 0 + 0)| / 2 = 48/2 = <<48/2=24>>24 - DNSFLEX

Understanding the Context

Then the area is:
Area = |(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)| / 2

This method efficiently computes area without needing base-height measurements, making it especially useful for programming and coordinate geometry problems.

Applying the Numbers

Let’s break down the values given in the problem:
Points are defined as:

• A = (0, 0)
  
• B = (8, 6)
  
• C = (3, 0)

Key Insights

Substitute into the formula:

Area = |(0×6 + 8×0 + 3×0) - (0×8 + 0×3 + 6×0)| / 2
= |(0 + 0 + 0) - (0 + 0 + 0)| / 2
= |0 - 0| / 2
= 0 / 2 = 0

Wait — the calculation yields 0? Not quite. In reality, using the standard determinant approach, the area is better calculated using:
Area = |(x₁(y₂−y₃) + x₂(y₃−y₁) + x₃(y₁−y₂))| / 2

Let’s recalculate with this form for clarity:
Area = |0(6−0) + 8(0−0) + 3(0−6)| / 2
= |0 + 0 + 3(-6)| / 2
= |-18| / 2 = 18 / 2 = <<18/2=9>>9

So, the actual area is 9 square units, not zero — the original expression format appears to simplify incorrectly due to coordinate choice or formula misalignment.

Final Thoughts

Why This Formula Many Get Confused

This example highlights a common pitfall: simple plug-in errors. When x₁ = y₁ = 0 and the rest of the coordinates are off, miscalculating pairwise products can return zero unne Glasgow correctly. Using the fully expanded area formula prevents confusion and ensures accuracy.

Practical Application in Real Life

This method applies to any triangle defined by 3 points on a plane:

• GPS coordinates for land surveying
  
• Computer graphics for rendering 2D shapes
  
• Robotics path planning using spatial coordinates

Final Thoughts

While the initial expression simplified back to zero due to coordinate alignment (meaning points may be collinear), learning this technique prepares you to tackle a broader range of geometric problems efficiently. Mastery of coordinate geometry unlocks deeper understanding in math, physics, engineering, and computer science.

Summary: Using the determinant formula
Area = |(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)| / 2
for points (0,0), (8,6), and (3,0) yields 9 square units — a clear, step-by-step solution defusing confusion from simple coordinate input.
