Calculating Areas of Shapes

The video tutorial covers the calculation of areas for different geometric shapes: parallelograms, triangles, and trapezoids. It begins with a review of previous notes and introduces the formulas for each shape's area. The teacher provides step-by-step examples for calculating the area of each shape, emphasizing the importance of identifying the base and height, especially in triangles and trapezoids. The tutorial concludes with instructions for an assignment related to the covered material.

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

• Base plus height

• Base divided by height

• Base minus height

• Base times height

In a parallelogram, which line is considered the height?

• The shortest line

• The line parallel to the base

• The line with a right angle to the base

• The longest line

How do you calculate the area of a triangle?

• Base times height

• Base plus height

• Base times height divided by 2

• Base minus height

What is the base of a triangle if the height is 8 and the area is 56?

• 7

• 14

• 28

• 16

Which part of a trapezoid is not used in calculating its area?

• The parallel sides

• The slanted side

• The base

• The height

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

• Multiply the height by the base

• Divide the base by the height

• Add the lengths of the two parallel sides

• Subtract the height from the base

If a trapezoid has bases of 3 and 9, and a height of 8.5, what is its area?

• 408

• 102

• 51

• 204

What is the final step in calculating the area of a trapezoid?

• Multiply by 2

• Divide by 2

• Add the height

• Subtract the height
