Show hintHide hint
Use the basic area formula.
Question 2.
What is the area using Heron's formula for a triangle with sides 3, 4, and 5?
Show hintHide hint
First calculate the semiperimeter.
3Question 3.
What is the formula for the area of a triangle using base and height?
- Area = b × h
- Area = 1/2 × b × h
- Area = b + h
Show hintHide hint
Think about the height in relation to the base.
4Question 4.
True or False: Heron's formula can only be used if height is known.
- True
- False
Show hintHide hint
Remember that Heron's formula relates to side lengths.
Question 5.
Calculate the area of a scalable triangle where one vertex is at the origin (0, 0), another vertex is at (5, 0), and the third vertex is at (2, 4).
Show hintHide hint
Use the formula with coordinates to determine area based on vertices.
Question 6.
Propose a scenario where a triangle forms within a rectangle, and you must calculate the area of both using respective formulas. Explain how they relate to each other.
