What is formula for the area of a trapezoid

The video tutorial covers the properties and area calculations of parallelograms, triangles, and trapezoids. It begins with a recap of parallelogram properties, emphasizing that any parallelogram has two sets of parallel lines and its area is calculated as base times height. The tutorial then explains that the area of a triangle is half that of a parallelogram. The focus shifts to trapezoids, highlighting that they have only one set of parallel lines and different base lengths. The area of a trapezoid is calculated using the formula: 1/2 times the height times the sum of the two bases.

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

• Base plus height

• Base minus height

• Base times height

• 1/2 base times height

How is the area of a triangle related to the area of a parallelogram?

• It is twice the area of a parallelogram

• It is half the area of a parallelogram

• It is the same as the area of a parallelogram

• It is unrelated to the area of a parallelogram

What is a key characteristic of a trapezoid?

• All sides are equal

• It has one set of parallel lines

• It has no parallel lines

• It has two sets of parallel lines

In a trapezoid, how do the lengths of the bases compare?

• They are always parallel

• They are both zero

• They are always equal

• They are different lengths

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

• Height divided by base one plus base two

• 1/2 times height times (base one plus base two)

• Base one plus base two times height

• Base one times base two times height
