Finding the Area of a Triangle

The video tutorial guides viewers through calculating the area of a triangle. It begins by prompting viewers to attempt solving the problem independently. The instructor then explains the formula for the area of a triangle, which involves multiplying the base by the height and dividing by two. The base and height are identified as 18 and 6, respectively. The instructor performs the calculation, resulting in an area of 54 square units, and concludes the lesson.

What is the first step in solving for the area of a triangle?

• Identify the base and height

• Square the base and multiply by the height

• Multiply the base by the height

• Divide the product of base and height by 2

What is the formula for the area of a triangle?

• 1/2 base times height

• Base squared

• Base times height

• Base plus height

How is the base of the triangle identified in the video?

• It is the side opposite to the right angle

• It is calculated using Pythagoras theorem

• It is given as 18 units

• It is the longest side of the triangle

What is the height of the triangle as given in the video?

• 12 units

• 6 units

• 9 units

• 18 units

How do you calculate half of the base's length?

• Both A and B are correct

• Divide by 2

• Subtract from the total area

• Multiply by 0.5

What is the final area of the triangle?

• 72 square units

• 54 square units

• 36 square units
