SUMMARY

The area of a triangle with a base of 2 and 3/4 (or 11/4) and a height of 4/9 is calculated using the formula 1/2 * (b*h). The correct calculation yields an area of 11/18. The discussion confirms that the solution is accurate, emphasizing the importance of ensuring that the height is perpendicular to the base for correct area calculation.

PREREQUISITES
  • Understanding of basic geometry concepts, specifically triangle area calculation.
  • Familiarity with fractional arithmetic and simplification.
  • Knowledge of the formula for the area of a triangle: 1/2 * (base * height).
  • Ability to identify perpendicular heights in triangle geometry.
NEXT STEPS
  • Study the properties of different types of triangles, including equilateral and right triangles.
  • Learn about the implications of slanted heights in triangle area calculations.
  • Explore advanced geometric concepts such as Heron's formula for area calculation.
  • Practice solving triangle area problems with varying base and height configurations.
USEFUL FOR

Students studying geometry, educators teaching triangle properties, and anyone needing to verify triangle area calculations.

What you've done is correct given how you've described the problem. Are you just unsure about your answer? Because it's right.
 
Yeah, I just want to make sure I was solving these problems correctly, and I had to have a confirm :) ,thankyou!

Just make sure the height is perpendicular (right angled) to the base. If you're taking the height as being slanted to the base, such as having an equilateral triangle with the length of a side given, you can't just say the height is the same length as the base.
