Find the area of an oblique triangle - Online tutor - Free Math Videos

The video tutorial covers the calculation of area for different shapes, including squares, rectangles, and triangles. It emphasizes the importance of using the correct formula for right and oblique triangles to avoid confusion. The tutorial explains that while the formulas for area may seem similar, they must be applied carefully depending on the type of triangle. The video provides examples to illustrate the correct application of these formulas.

What is the formula for calculating the area of a rectangle?

• Area = base + height

• Area = 1/2 base x height

• Area = length x width

• Area = length + width

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

• Area = base + height

• Area = 1/2 base x height

• Area = base x height

• Area = length x width

In a right triangle, which of the following statements is true?

• Neither formula can be used.

• Both 'base x height' and 'length x width' can be used interchangeably.

• Only 'length x width' can be used to find the area.

• Only 'base x height' can be used to find the area.

When calculating the area of an oblique triangle, which formula should be used?

• Area = 1/2 base x height

• Area = base + height

• Area = base x height

• Area = length x width

Why is it important to use the correct formula for oblique triangles?

• To ensure the area is calculated as zero.

• To avoid confusion with other sides of the triangle.

• To use the same formula as for squares.

• To make the calculation faster.
