Find the area of oblique triangle using heron's formula

The video tutorial explains how to use Heron's formula to calculate the area of a triangle. It provides a step-by-step guide on applying the formula, highlights common mistakes students make with parentheses, and offers tips for simplifying calculations. The tutorial concludes with a reminder about unit considerations when presenting the final result.

What is the formula for calculating the semi-perimeter 's' in Heron's formula?

• (a + b) / 2

• a * b * c

• (a + b + c) / 2

• a + b + c

Why is it important to use parentheses when entering Heron's formula into a calculator?

• To reduce the number of steps

• To make the calculation faster

• To avoid syntax errors

• To ensure the correct order of operations

What is a common mistake students make when using calculators for Heron's formula?

• Forgetting to add the sides

• Misplacing the decimal point

• Incorrect use of parentheses

• Using the wrong formula

What is the simplified expression for the area calculation in the given example?

• Square root of 8.5 times 3.5 times 0.5 times 4.5

• Square root of 8.5 times 3.5 times 0.5

• Square root of 8.5 times 5 times 4.5

• Square root of 8.5 times 3.5 times 4.5

What should you remember to include in your answer if the measurements are in feet?

• The answer should be in meters

• The answer should be in meters squared
