Area of Trapezoids

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height

Front

What are the two bases of a trapezoid?

Back

The two parallel sides of a trapezoid.

Front

How do you find the height of a trapezoid?

Back

The height is the perpendicular distance between the two bases.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

True or False: A trapezoid can have only one pair of parallel sides.

Back

True

Front

If the bases of a trapezoid are 10 cm and 14 cm, and the height is 5 cm, what is the area?

Back

Area = (1/2) * (10 + 14) * 5 = 60 cm²

Front

What is the total length of the bases in a trapezoid?

Back

It is the sum of the lengths of the two parallel sides.

Front

If a trapezoid has an area of 84 m² and the height is 4 m, what is the total length of the bases?

Back

Total length of bases = (Area * 2) / Height = (84 * 2) / 4 = 42 m.

Front

What is the relationship between the height and the area of a trapezoid?

Back

The area increases with an increase in height, assuming the bases remain constant.

Front

If one base of a trapezoid is 8 cm and the other is 12 cm, what is the average length of the bases?

Back

Average length of bases = (8 + 12) / 2 = 10 cm.
