Understanding the Area of a Trapezoid

What is a trapezoid?

• A triangle with one pair of parallel sides

• A quadrilateral with two pairs of parallel sides

• A polygon with no parallel sides

• A quadrilateral with one pair of parallel sides

How can the area of a trapezoid be initially calculated?

• By dividing it into two rectangles

• By using the Pythagorean theorem

• By dividing it into two triangles

• By calculating the perimeter first

What is the area of triangle A if its base is 7 and height is 4?

• 28 square centimeters

• 14 square centimeters

• 21 square centimeters

• 10 square centimeters

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

• (Base A + Base B) x Height

• (Base A + Base B) x Height / 2

• Base x Height / 2

• Base x Height

Why is the formula for the area of a trapezoid more efficient?

• It uses only one triangle

• It calculates the perimeter first

• It avoids using any triangles

• It requires fewer calculations
