How to find the area of a triangle

The video tutorial explains how to calculate the area of a triangle. It begins by emphasizing the importance of identifying the figure and writing down the correct formula. The instructor discusses the need to determine the base and height of the triangle, avoiding confusion from other numbers. The calculation is demonstrated using a calculator, resulting in an area of 212.5 square centimeters. The tutorial concludes by stressing the importance of including units in the final answer.

Which of the following is NOT a formula discussed in the class for calculating area?

• Circle

• Parallelogram

• Trapezoid

• Kite

What is the first step in calculating the area of a triangle?

• Identifying the type of figure

• Identifying the height

• Writing down the formula

• Identifying the base

How do you determine the base of a triangle when given multiple numbers?

• Identify the side perpendicular to the height

• Use the number that appears first

• Choose the longest side

• Select the number closest to the height

What is the correct formula for calculating the area of a triangle?

• Area = 1/2 * base * height

• Area = base * height

• Area = base + height

• Area = base - height

Why is it important to include units when writing the area of a triangle?
