How to find the area of an oblique triangle

The video tutorial explains how to find the area of a triangle by identifying the base and height. It discusses the flexibility in choosing different bases and the importance of knowing or finding the corresponding height. The tutorial walks through calculations using specific base and height values, demonstrating the process of determining the area step-by-step.

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

• Calculate the perimeter

• Identify the type of triangle

• Write down the formula

• Measure the angles

Why is it important to choose the correct base when calculating the area of a triangle?

• The base affects the color of the triangle

• The base is always the longest side

• The base determines the type of triangle

• The base must correspond with a known or calculable height

What was the final base chosen for the triangle in the example?

• 4.5

• 11.25

• 12

• 13.7

What is the formula used to calculate the area of a triangle?

• Area = 1/2 * base * height

• Area = base * height

• Area = base - height

• Area = base + height

What was the calculated area of the triangle in the example?

• 25.31

• 54

• 4.5

• 11.25
